In Harry Potter and the Deathly Hallows,Hermioneused an UndetectableExtension Charm on her beadedhandbag,significantly enlarging the bag's internal dimensions without affecting its physical size.
As well, the mass of the objects placed in her handbag is negated, making the bag easy to carry. Bags similar to this appear in other contexts, such as the bag of holding in Dungeons and Dragons or the magic satchel in many other games, and Felix the Cat's bag of tricks. Mary Poppins also seems to have a handbag of similar uses. Hermione uses it to carry everything they need when they travel across the United Kingdom on their hunt for Horcruxes.
Mokeskin pouch
Mokeskin pouches are a type of draw-string pouch that can be operated only by the owner. Harry receives one as his 17th birthday present from Hagrid, using it to store several items of personal significance, such as the Golden Snitch, his broken wand, the false locket, the shard of Sirius' mirror and the Marauders' Map.
Moody's Magical Trunk
Alastor Moody owns a strangely bewitched magical trunk. It has seven locks on it, and the trunk opens to a different assortment of objects for each lock. Most notably, though, the seventh compartment is about 3 m deep (possibly because of the use of an Undetectable Extension Charm), and is where Barty Crouch Jr. imprisoned the real Moody. Other compartments contain spellbooks, Dark Detectors, and Moody's invisibility cloak.
Pensieve
A Pensieve is a stone basin used to review memories. Covered in mystic runes, it contains memories whose physical form is neither gas nor liquid. A witch or wizard can extract their own or another's memories, store them in the Pensieve, and review them later. It also relieves the mind when it becomes cluttered with information. Anyone can examine the memories in the Pensieve, which also allows viewers to fully immerse themselves in the memories stored within, much like a magical form of virtual reality.
Users of these devices view the memories from a third-person-point-of-view, providing a near-omniscient perspective of the events preserved.
The memories contained in the Pensieve have the appearance of silver threads. Memories that have deteriorated due to age, or that were heavily manipulated or tampered with to alter perspectives (such as Slughorn's), may appear thick and jelly-like and offer obscured viewing. Memories are not limited to just those of humans, since Hokey the house-elf provided Dumbledore with a memory as well. It makes its last appearance in Deathly Hallows when Harry uses it to uncover the truth about Snape.
In the fourth film, the Pensieve in Dumbledore's office conforms to the description given in the novel. However, in the sixth and eighth films, it appears as a shallow metal dish, floating in midair and filled with a mercury-like liquid. During the eighth film, Harry removes it from the stone basin so he can use it to examine Snape's memories.
Today, The Weasleys & The Grandma have been reading about some magical objects that you canfind inHogwarts, the prank ones. Before this, they have practised ThePassive in English and some vocabulary.
Prank objects from Weasleys' Wizard Wheezes are made and designed by the owners of the shop, Fred and George, who test their new creations on themselves and other Hogwarts students.
-Weasley's Wild-fire Whiz-Bangs are enchanted fireworks that have overly spectacular and remarkable effects. In the books, they are engineered to not generate any amounts of heat, light, or noise that could be harmful. In the film of Order of the Phoenix, however, the fireworks create a large fiery dragon that attacks Umbridge, burning her and leaving her covered in soot.
-Skiving Snackboxes are sweets that are designed to make the eater temporarily ill in order to skip or skive off class. Each variety of Snackboxes causes a different effect, such as vomiting, fainting or developing nosebleeds. One end of the sweet causes the malady, while the other end subsequently cures it. The snackboxes include: Nosebleed Nougat, Fever Fudge, Fainting Fancies, Blood Blisterpods and Puking Pastilles.
-Patented Daydream Charms are kits that put the user into a realistic 30-minute daydream which they imagine, and can easily be customised so as to be fitted into any lesson.
-A Headless Hat creates a limited field of invisibility that covers the wearer's head, giving them the appearance of not having a head. Its counterpart is a Shield Hat, which deflects minor hexes and curses. Though Fred and George design the Shield Hat to be a trick item, Ministry officials are impressed by its practical value and order 500 of them for the protection of the Aurors. Shield Cloaks and Shield Gloves are also on sale following the Shield Hat's success.
-Trick Wands are magical fake wands that turn into a silly item (rubber chickens, tin parrots, etc.) when someone tries to use them. More expensive varieties beat the unwary user about the head and neck.
-Ton-Tongue Toffees make the eater's tongue temporarily grow to an alarmingly large size, as read about in Goblet of Fire when Fred accidentally drops some in front of Dudley, who subsequently eats one they forgot to retrieve.
-Canary Creams make the eater turn briefly into a large canary; when the effect wears off, the person moults and returns to normal.
-U-No-Poo causes the consumer to have constipation, or as Fred and George refer to it: The constipation sensation that's gripping the nation. Its name is a play on You-Know-Who, commonly used to refer to Voldemort.
-Extendable Ears are long flesh-coloured strings, one end of which is inserted into a user's ear and the other end placed further away towards a conversation or sound. Much like a listening device, the user will be able to hear the sounds as if they were much closer to the source. They were first introduced by Fred and George Weasley in Harry Potter and the Order of the Phoenix, when they used the ears to listen to the Order's meetings, until one was destroyed (and eaten) by Crookshanks.
-Portable Swamps are, as the name suggests, realistic pop-up swamps. They were first seen in Order of the Phoenix after Umbridge is named Headmistress. Fred and George set one off in a corridor, partly as a distraction for Umbridge so Harry can use her fireplace, and partly to just cause general mayhem. They seem to be reasonably difficult to remove: Umbridge cannot remove it and forces Filch to punt students across, while Professor Flitwick vanishes it almost instantly later on in the novel. He leaves a small patch untouched as a tribute to Fred and George, who have left Hogwarts by this point.
-Decoy Detonators are described as black horn type objects that will run out of sight, and make a noise giving the user a good distraction. Introduced in Harry Potter and the Half-Blood Prince. First used by Harry while breaking into Dolores Umbridge's office at the Ministry of Magic in Harry Potter and the Deathly Hallows.
-Guaranteed Ten-Second Pimple Vanisher
-Pygmy Puffs (miniature Puffskeins)
-Edible Dark Marks
There are also prank items which the Weasleys import from elsewhere, such as:
-Peruvian Instant Darkness Powder, which throws an area into darkness that cannot be penetrated by wand light or any magical means, although the effect wears off in a few minutes. Draco Malfoy uses it to avoid members of Dumbledore's Army in Half-Blood Prince. It is also used in the Half-Blood Prince film by Harry in order to gain access to the luggage space above Draco Malfoy's table on the Hogwarts Express.
Zonko's Joke Shop was a favourite place for Hogwarts students to shop on Hogsmeade trips. It carried jokes and tricks to fulfil even Fred and George's wildest dreams. Such products include Hiccough Sweets, Frog Spawn Soap, and Nose-Biting Teacups. Fred and George tried to buy the place to expand their shop in Hogsmeade during Harry's sixth year, but they turned it down due to the dark times coming up.
Other prank objects
Other prank objects include Belch Powder, Dungbombs (which explode and cause a large and extremely smelly mess), and Ever-Bashing Boomerangs (which hit their target repeatedly after being thrown). Fanged Frisbees are quite literally normal Frisbees with fangs and are first mentioned in Goblet of Fire as one of Filch's newest restricted items during Dumbledore's start-of-term speech. However, they make their first appearance in Half-Blood Prince when Ron whirled one around the Gryffindor common room, it changed course with a mind of its own, and took a bite out of a tapestry. Most of these objects are banned at Hogwarts due to the possibility of injury.
More objects include Screaming Yo-Yos, which scream very loudly when worked, and Stink Pellets, which are used to distract prefects and teachers, and give a most unpleasant smell.
Today, The Grandma has been reading about some magical objects that you canfind inHogwarts, the mirrors.
The Mirror of Erised
The Mirror of Erised is a mystical mirror discovered by Harry in an abandoned classroom in Philosopher'sStone.
On it is inscribed erised stra ehru oyt ube cafru oyt on wohsi. When mirrored and correctly spaced, this reads I show not your face but your heart's desire. As erisedreversed is desire, it is the Mirror of Desire. Harry, upon encountering the Mirror, can see his parents, as well as what appears to be a crowd of relatives. The last thing Harry saw in the mirror was Voldemort defeated.
Ron sees himself as Head Boy and Quidditch Captain holding the House Cup, revealing his wish to escape from the shadow of his highly successful older brothers. Dumbledore cautions Harry that the Mirror gives neither knowledge nor truth, merely showing the viewer's deepest desire, and that men have wasted their lives away before it, entranced by what they see.
Dumbledore claims to see himself holding a pair of socks he always wanted, telling Harry that one can never have enough socks, and lamenting that he did not receive any for Christmas, since people will insist on giving him books.
The Mirror of Erised was the final protection given to the Philosopher's Stone in the first book. Dumbledore hid the Mirror and hid the Stone inside it, knowing that only a person who wanted to find but not use the Stone would be able to obtain it. Anyone else would see themselves making an Elixir of Life or turning things to gold, rather than actually finding the Stone, and would be unable to obtain it. What happens to the mirror afterwards is unknown.
In Order of the Phoenix, Sirius gives Harry a mirror he originally used to communicate with James while they were in separate detentions. That mirror is a part of a set of Two-way Mirrors that are activated by holding one of them and saying the name of the other possessor, causing his or her face to appear on the caller's mirror and vice versa. Harry receives this mirror from Sirius in a package after spending his Christmas holiday at Grimmauld Place. Harry, at first, chooses not to open the package, although he does discover the mirror after Sirius' death, by which point it is no longer functional. It makes its second appearance in Deathly Hallows when Mundungus Fletcher loots Grimmauld Place and sells Sirius' mirror to Aberforth Dumbledore, who uses it to watch out for Harry in Deathly Hallows. When Harry desperately cries for help to a shard of the magical mirror (which broke in the bottom of his trunk), a brilliant blue eye belonging to Aberforth (which Harry mistakes for Albus' eye), appears and he sends Dobby, who arrives to help Harry escape from Malfoy Manor to Shell Cottage.
The Mirror will be moved to a new home tomorrow, Harry, and I ask you not to go looking for it again. If you ever do run across it, you will now be prepared. It does not do to dwell on dreams and forget to live, remember that. Now, why don't you put that admirable cloak back on and get off to bed.
Today, The Grandma has been reading about some legendary magical artifacts that you can find inHogwarts.
The Goblet of Fire
The Goblet of Fire is a goblet made of wood and is used at the beginning of every Triwizard Tournament. It is used solely to choose the participating school champions, serving as an impartial judge.
Slips of parchment with the names of potential candidates are placed in the Goblet and, at the designated time, a representative from each school is chosen when the slip of parchment containing their name spouts forth from the Goblet in a fountain of magical fire.
Barty Crouch Jr., masquerading as Professor Moody, stated that the Goblet of Fire was an exceptionally powerful magical object and it is very difficult to hoodwink, unless someone uses an exceptionally strong Confundus Charm.
During its use in Goblet of Fire, it is placed in the entrance hall and surrounded by an Age Line, a charm placed by Dumbledore to prevent underage wizards from entering the tournament. Anyone underage would grow a long white beard, as the Weasley twins demonstrated when they attempted to fool the goblet with an Ageing Potion. When not in use, the Goblet is kept in a jewelled casket in Dumbledore's closet.
The Sword of Godric Gryffindor is a goblin-made sword adorned with large rubies on the pommel. It was once owned by Godric Gryffindor, one of the medieval founders of Hogwarts. In Chamber of Secrets, Harry draws the Sword out of the Sorting Hat to battle and kill Salazar Slytherin's basilisk.
When Dumbledore learns of Harry's concern that he does not belong in the House of Gryffindor, in part at being parseltongue like Lord Voldemort, the headmaster is able to put the boy's concerns at ease by telling him only a true member of that house could have summoned that sword in his time of need. The sword also plays a key role in Deathly Hallows, where it is revealed to have become imbued with Basilisk venom following its use against the Basilisk, as it only takes in that which makes it stronger. It is subsequently used to destroy three of Voldemort's Horcruxes.
Because the Sword was goblin-forged, it is indestructible. According to Griphook the goblin, the Sword was originally forged by the goblin Ragnuk the First and stolen by Gryffindor. The Sword was taken by Griphook when the Sword fell from Harry's grasp during the raid on Bellatrix Lestrange's vault in book seven. The sword returned to wizard hands when Neville pulled it out of the Sorting Hat and used it to decapitate Nagini, Voldemort's snake. This shows that no matter where the sword happened to be at the time, it will reappear in the Hat when a true member of Gryffindor house is in need of it.
Godric Gryffindor commissioned Ragnuk the First to make the sword for him under his specifications. Once Ragnuk had made the sword, he was so fond of it that after he had presented it to Gryffindor, he told the goblins it had been stolen and sent minions to retrieve it for him. Gryffindor defeated the goblins using magic and instead of killing them, he bewitched them to go back to Ragnuk and say that if he tried to take the sword again, he would use it against them. The king took the threat seriously, but still insisted it had been stolen from him until the day he died.
It is mentioned in the Deathly Hallows that the Sword of Gryffindor is supposed to be in Bellatrix Lestrange's vault, placed there by Severus Snape. Unknown to Bellatrix, that sword was only a replica. When Harry, Ron and Hermione were captured and brought to Malfoy Manor, she spotted the sword near one of the Snatchers, who intended to keep it. She killed him and forced the rest out of the room, then tortured Hermione for information about the sword. But at Harry's request, Griphook lied and said that the sword was a forgery. Bellatrix's reaction to having her vault possibly broken into convinced Harry that the Horcrux was also placed in her vault.
Based upon the ancient alchemical idea of the philosopher's stone, the stone is owned by Nicolas Flamel and first mentioned in Harry Potter and the Philosopher's Stone. The stone is legendary in that it changes all metals to gold, and can be used to brew a potion called the Elixir of Life, making the drinker immortal. The Philosopher's Stone is seen only in the first and last book, although it is referenced several times throughout the series. It was destroyed at the end of the first book by Dumbledore with Flamel's agreement.
The Sorting Hat is a sapient artefact used at Hogwarts, which reads minds to determine which of the four school houses -Gryffindor, Hufflepuff, Ravenclaw or Slytherin- each new student is to be assigned for their years at Hogwarts. The hat resembles a dilapidated conical leather wide-brimmed wizard's hat, with folds and tears that make it appear to have eyes and a mouth. During the opening banquet at the beginning of each school year, the Hat is placed on every first-year student's head. The Hat announces its choice aloud, and the student joins the selected house. The Hat speaks to the student while they are being sorted and is willing to take the student's preferences into account when it makes its decision. Sometimes it does not have the need to do so: for instance, the Hat barely touched Draco Malfoy's head before sending him to Slytherin. The Sorting Hat had a difficult time placing Harry, almost placing him into Slytherin house before he requested specifically and emphatically not to be. The Hat instead placed him into Gryffindor, the house of his parents.
The Sorting Hat originally belonged to Godric Gryffindor, one of the four founders of Hogwarts. The four founders used to hand-pick the students for their houses, but then realised someone else would have to do it after they died, so Gryffindor took off his hat, enchanted it, and let it choose. Since then, the Sorting Hat has always been used to choose which house the students are put in. Due to its age, it appears patched and frayed and extremely dirty. Before Sorting the students each year, the hat recites a new introductory song. These songs occasionally warn of danger to come, as in Order of the Phoenix. The Sorting Hat's songs vary in length and content, but always include a brief description of each house.
The Sorting Hat has shown the ability to conjure the Sword of Gryffindor from under its brim, as shown in two instances. Both times it is used to kill snakes; in Chamber of Secrets, it provides the sword to Harry to kill the Basilisk, and in Deathly Hallows, it delivers the sword to Neville. Dumbledore makes it clear in Chamber of Secrets that only a true Gryffindor can summon the sword in this fashion. In Deathly Hallows the Sorting Hat is set on fire by Voldemort, although it appears the hat was not destroyed, as Neville was able to draw the Sword of Gryffindor from it immediately after and behead Voldemort's snake Nagini. In the epilogue at the end of Deathly Hallows, the Hat's survival is confirmed, as Harry tells his youngest son that the Hat would take his preference into consideration.
Today, The Grandma has been reading about some games that you can play inHogwarts.
Exploding Snap
Exploding Snap is a wizarding cardgame in which the cards spontaneously explode during games.
The game is popular with Hogwarts students.
In Chamber of Secrets, Harry and Ron are held back from investigating why spiders were fleeing Hogwarts because Fred and George delayed them with this game. Ron later singed his eyebrows while building a card house with Exploding Snap cards.
In Order of the Phoenix, Lee Jordan is punished by Dolores Umbridge for saying that she cannot tell them off for playing this game, as one of her Educational Decrees states that teachers can only talk to students about the subjects they are paid to teach. In Cursed Child, Ginny remembers playing this game with Harry following the events of Chamber of Secrets and notes that it helped her to recover from the trauma (all the other students avoided her after learning the truth).
Gobstones
Gobstones is one of the many magical games played by young wizards in the books, along with Wizard's Chess and Exploding Snap.
Gobstones is similar to the games of marbles and pétanque, except that in Gobstones, the balls spit, or gob, a foul-smelling liquid in the face of the opposing player when they lose a point. Hogwarts students are seen playing Gobstones throughout the books, and there is even a Gobstones Club at the school. It is also noted in the Harry Potter series that Eileen Prince (Snape's mother) was captain of Hogwarts' Gobstone Club, as a student, at age 15.
Quidditch balls
The Quidditch balls consist of a Quaffle, a large red ball (and the only one not bewitched to fly on its own) which the Chasers need to get through the three hoops on the field, gaining ten points each time this successfully occurs; two Bludgers, which fly around attempting to disturb the game and knock people off their brooms, and which the Beaters hit away from teammates and towards the opposing team; and the Golden Snitch, a very fast and difficult-to-see golden orb the size of a walnut with wings, which the Seeker on each team must capture to finish the game and gain 150 points. The Quidditch players wear gloves, leg pads, padded head guards, and occasionally goggles.
Self-Shuffling Playing Cards
In Chamber of Secrets, a pack of Self-Shuffling Cards is mentioned as one of the various objects littering the floor of Ron's room in the Burrow.
Wizard's Chess
Wizard's Chess is played with pieces and a board identical to Chess. The rules are also unchanged. The pieces are magically animated, and they violently attack each other when performing a capture, by knocking the captured piece out and dragging it off the board. The players order the pieces to move using algebraic chess notation.
Ron has a wizard's chess set left to him by his grandfather, and Harry first plays with pieces borrowed from Seamus Finnigan, which kept shouting him advice because they did not trust him. Harry later gets a set of his own during his first Christmas at Hogwarts.
During the 16th chapter of Philosopher's Stone, Harry, Ron and Hermione become human chess pieces in a life-sized game of Wizard's Chess, which Harry wins thanks to Ron's advice and sacrifice as a piece. In the films, the chess pieces are depicted using replicas of Lewis Chessmen.
Today, The Grandma has been reading about magical objects that you can find in Hogwarts.
Alastor Moody's Eyeball
Alastor Moody lost his eye sometime during the First Wizarding War. He replaced it with an enchanted glass eyeball. In the film HarryPotter and the Goblet of Fire, the eyeball is blue, and replaces his left eye. In the books, it replaces his right eye.
The eyeball has many magical enchantments on it, giving it the ability to see through walls and other solid objects, notably invisibility cloaks, can rotate 360 degrees inside his head, and can be fully removed from his head. The eyeball is also very sensitive, as after Barty Crouch Jr. was caught Moody complained that the eyeball kept sticking ever since that scum wore it.
After Moody was killed on 27 July 1997 during the plan to move Harry from 4 Privet Drive, the eyeball was given to Dolores Umbridge after his body was recovered by Death Eaters. She placed the eyeball in her door so that she could keep an eye on her employees. Harry stole the eyeball during his raid on the ministry, and buried it in the forest, where the Quidditch World Cup was held.
A Foe-glass is a mirror that detects and shows its owner's enemies in or out of focus, depending on how close they are. Barty Crouch Jr., while impersonating Moody, says that when the whites of their eyes are visible, he is in trouble. When Crouch Jr. is attacking Harry after the third task, Harry sees Snape, McGonagall and Dumbledore approach the room in the mirror before they show up.
A Foe-glass is hanging in the Room of Requirement in Harry Potter and the Order of the Phoenix when Harry uses the Room for D.A. meetings. Like all dark detectors, it can be fooled, as mentioned by Harry at the beginning of the first D.A. meeting.
The Marauder's Map is a magical map of Hogwarts created by Remus Lupin, Peter Pettigrew, Sirius Black, and James Potter (respectively nicknamed "Moony", "Wormtail", "Padfoot", and "Prongs") while they were students at Hogwarts.
In Harry Potter and the Prisoner of Azkaban, Fred and George Weasley give the map to Harry so he can travel to Hogsmeade through a hidden passageway. The twins had previously stolen the map from a drawer in Filch's office that contained dangerous confiscated objects; it is revealed by Lupin that Filch probably knew what it was but not how to work it. Snape later finds the map in Harry's possession and tries to force it to reveal its secrets, but the map insults him. Lupin, the Defence Against the Dark Arts teacher at the time, is called upon to investigate this dark object, and confiscates it to keep Harry safe. Later he returns it to Harry after resigning his post at Hogwarts. From then on, the map becomes one of Harry's most useful tools in his ongoing adventures.
When not in use, the Map is simply a blank piece of parchment. It can be activated by pointing a wand at it and saying, I solemnly swear that I am up to no good, at which point the message Messrs. Moony, Wormtail, Padfoot and Prongs, purveyors of aids to magical mischief-makers, are proud to present the Marauder's Map appears, along with a detailed layout of Hogwarts. The map is restored to its original blank state by saying Mischief managed. The map displays the location of everyone within the castle and its grounds. It includes locations of secret passageways and instructions on how to access them.
Several locations like the Room of Requirement and the Chamber of Secrets do not appear on the map, either as the Marauders did not have any knowledge of them, or, in the case of the former, they are not a fixed location. Animagus disguises, Polyjuice Potion, and invisibility cloaks cannot fool the map.
In Prisoner of Azkaban, Peter Pettigrew, who is supposed to be dead but as an Animagus has transformed into a rat, shows up on the map under his real name.
In Goblet of Fire, Barty Crouch Jr. is using Polyjuice Potion to disguise himself as Moody. At one point, Harry catches him on the map searching Snape's office for ingredients, but mistakes him for his father, Barty Crouch Sr., as the map cannot differentiate between two individuals who share a first and last name. Crouch Jr. subsequently confiscates the map from Harry, and uses it to track down and murder his own father when his father breaks free of the Imperius Curse and comes to Hogwarts looking for him.
On the prop version of the map made for the films, the lines are made up of what at first glance are just random letters, but upon closer inspection are Latin words.
Remus Lupin (Moony) Peter Pettigrew (Wormtail) Sirius Black (Padfoot) James Potter (Prongs)
Probity Probe
A Probity Probe detects spells of concealment and hidden magical objects.The detector made its first appearance in Order of the Phoenix at the Ministry of Magic as a thin golden rod. After Voldemort's return, Probes are used as part of the increased security at Gringotts Bank as well as for scanning the students of Hogwarts for Dark objects. They are last seen when Harry, Ron, and Hermione arrive at Gringotts in Deathly Hallows to rob Bellatrix Lestrange's vault of one of Voldemort's Horcruxes.
A Remembrall is a small, clear orb, about the size of a large marble, containing smoke that turns red when it detects that the person holding it has forgotten something.
It does not tell the holder what has been forgotten. The forgetful Neville Longbottom is sent a Remembrall by his grandmother in Philosopher's Stone. Remembralls are forbidden from being used during the O.W.L. exams.
A Revealer is a bright red eraser, used to make invisible ink appear. It made its first appearance in Chamber of Secrets when Hermione tried to make hidden writing appear in Tom Riddle's diary.
The Secrecy Sensor is a dark detector described as an object that looked something like an extra-squiggly, golden television aerial. It vibrates when it detects concealment and lies.
In Harry Potter and the Goblet of Fire, Barty Crouch Jr disguised as Alastor Moody mentions that it is no use here, of course, too much interference -students in every direction lying about why they haven't done their homework.
In Order of the Phoenix, Secrecy Sensors are used at the Atrium Desk in the Ministry of Magic upon visitors to the government locale. Later in the book, Harry mentions to Dumbledore's Army that they can be easily fooled like their other dark-detecting counterparts.
In Half-Blood Prince, due to Hogwarts' new stringent security measures, Argus Filch is assigned to inspect every student entering the castle with Secrecy Sensors. All the owls flying into Hogwarts are also placed under this measure to ensure that no Dark object enters the castle through mail. Hermione later explains that although Secrecy Sensors detect jinxes, curses, and Concealment Charms, they cannot detect love potions, as they are not considered Dark.
A Sneakoscope serves as a Dark Arts detector. The device is described as a miniature glass spinning-top that emits shrill noises in the presence of deception, for instance, when an untrustworthy person is near or when a deceitful event takes place nearby.
Sneakoscopes are introduced in Prisoner of Azkaban when Harry receives a pocket-sized version from Ron for his 13th birthday. Bill says that PocketSneakoscopes are unreliable, as it lit up and spun at dinner for apparently no reason, but Fred and George had put beetles in his soup without his knowledge. The sneakoscope appears again on the Hogwarts Express, and again in Harry and Ron's dormitory. Harry later discovers that Scabbers, Ron's rat, who is present each time the Sneakoscope is spinning, is actually Peter Pettigrew in Animagus form. In Goblet of Fire, Alastor Moody has several sneakoscopes that he somehow disabled, claiming, It wouldn't stop whistling, keeping them in one of the seven compartments of his magical trunk. The sneakoscopes' constant alerts in his presence were because he was Barty Crouch Jr. using Polyjuice Potion.
In Deathly Hallows, Hermione gives Harry a Sneakoscope for his seventeenth birthday which they later use as a lookout while in hiding.
The Weasleys have a special clock in their home, the Burrow, with nine hands, one for every member of the family. Instead of telling the time, the clock reveals the location or status of each family member. The known locations are: Home, School, Work, Travelling, Lost, Hospital, Prison, and Mortal Peril. The Weasleys are the only family mentioned in the series to own such a clock.Dumbledore calls the clockexcellent and seems impressed by it.
The location Mortal Peril is situated where the numeral 12 would normally be. Throughout the first five books, the hands change to reflect the varying statuses of the family members, but by the sixth book all nine hands point to mortal peril at all times, except when someone is travelling. Mrs. Weasley takes this to mean that with Voldemort's return, everyone is always in mortal peril, but she cannot verify this as she does not know anyone else who has a clock like hers.
After this, they have been reading about interesting and magical objects that we can find in Hogwarts.
Fake Galleons
In Harry Potter and the Order of the Phoenix, Hermione Granger creates fake, enchanted Galleons (wizard money) that are used for communication between members of Dumbledore's Army (DA). Like non-enchanted Galleons, the coins have numerals around the edge. On non-enchanted Galleons these serial numbers signify the goblin who cast the coin; on the enchanted Galleons, the numbers represent the time and date of the next DA meeting. Due to the coins being infused with a Protean Charm, once Harry Potter alters his, every coin changes to suit. The coins grow hot when the numbers change to alert the members to look at their coins.
InHarry Potter and the Half-Blood Prince, Draco Malfoy uses a pair of enchanted coins to bypass the communication limits imposed on Hogwarts, thus managing to keep in contact with Madam Rosmerta, whom he had placed under the Imperius Curse. Draco reveals he got the idea from Hermione's DA coins, which were themselves inspired by Lord Voldemort's use of the Dark Mark to communicate with his Death Eaters.
In Harry Potter and the Deathly Hallows, Neville Longbottom uses the DA's coins to alert people such as Luna Lovegood and Ginny Weasley that Harry, Ron and Hermione have returned to Hogwarts.
A Howler is a scarlet-red letter sent to signify extreme anger or to convey a message very loudly and publicly. When it is opened, the sender's voice, which has been magically magnified to a deafening volume, bellows a message at the recipient and then self-destructs itself by burning. If it is not opened or there is a delay in opening it, the letter smoulders, explodes violently, and shouts the message out even louder than normal. In the film version, the Howler folds itself into an origami-style set of lips and teeth and shouts the message out, and then shreds itself into scraps of paper before it burns itself.
In Harry Potter and the Chamber of Secrets, Ron Weasley receives a Howler from his mother, Molly Weasley, after he steals his father's enchanted car and flies it to Hogwarts with Harry. Neville Longbottom confesses that he had once gotten a Howler from his grandmother Augusta, stating that he ignored it and that the result was horrible. Subsequently, Neville receives another Howler from his grandmother after Sirius Black uses his list of passwords to enter the Gryffindor common room in Harry Potter and the Prisoner of Azkaban. Hermione receives one in Harry Potter and the Goblet of Fire after Rita Skeeter publishes a false article about a relationship between Hermione and Harry.
In Harry Potter and the Order of the Phoenix, Dumbledore sends Harry's aunt Petunia Dursley a Howler to remind her of the agreement to allow Harry to live at Privet Drive when Harry's Uncle Vernon attempts to throw him out.
RONALD WEASLEY! HOW DARE YOU STEAL THAT CAR! I AM ABSOLUTELY DISGUSTED! YOUR FATHER'S IS NOW FACING AN INQUIRY AT WORK, AND IT'S ENTIRELY YOUR FAULT! IF YOU PUT ANOTHER TOE OUT OF LINE, WE'LL BRING YOU STRAIGHT HOME!
Oh, and Ginny, dear, congratulations on making Gryffindor. Your father and I are so proud!!!
Molly Weasley
Deluminator
A deluminator is a device invented by Albus Dumbledore that resembles a cigarette lighter. It is used to remove or absorb (as well as return) the light from any light source to provide cover to the user. In Harry Potter and the Philosopher's Stone, Dumbledore uses the deluminator (then referred to as the Put-Outer)[HP1] to darken Privet Drive, where the Dursley family's house is located. It was seen in Order of the Phoenix where Dumbledore loans the deluminator to Alastor "Mad-Eye" Moody, who uses it when transporting Harry from the Dursleys' home to Sirius's home at Number 12, Grimmauld Place. In Half-Blood Prince, Dumbledore uses the deluminator again to darken Privet Drive before collecting Harry.
In Deathly Hallows, it is bequeathed to Ron by Dumbledore in his will. Later in the book, after Ron had left his friends in anger, the deluminator demonstrated an additional capability, similar to a homing device. Ron hears Hermione through the device as she says his name for the first time since he left, and, when he clicks it, the emitted ball of light enters his body and allows him to locate and apparate to the vicinity of Harry and Hermione's camp. J. K. Rowling stated Dumbledore left it to Ron because he believed he might have needed a little more guidance than Harry and Hermione.
Within the Harry Potter universe, an invisibility cloak is used to make the wearer invisible. All are very rare and expensive. In Fantastic Beasts and Where to Find Them it is said invisibility cloaks may be spun from pelts of the Demiguise. Invisibility cloaks can also be ordinary cloaks with a Disillusionment Charm or a Bedazzlement Hex placed on them. Over time, these cloaks will lose their invisibility ability, eventually becoming opaque and vulnerable to penetration by various spells. Moody is known to possess two invisibility cloaks. One of these was borrowed by Sturgis Podmore in the course of work for the Order of the Phoenix. Barty Crouch Sr. possessed one as well, which he used to hide his son Barty Crouch Jr. to prevent him from being found and returned to Azkaban, the wizarding prison.
Several times in the series, characters have been shown to either suspect or in some other fashion "sense" that Harry is wearing his cloak: Snape is seen to be suspicious when being followed by Harry, even reaching out to grab at (what appears to be) thin air; in Half-Blood Prince, Draco Malfoy realises Harry is in his train carriage and successfully immobilizes him with a Petrificus Totalus (Body-Bind) curse, as despite wearing his cloak Harry inadvertently moved objects near him; and in Chamber of Secrets, Albus Dumbledore senses Harry and Ron beneath it in Hagrid's cabin while talking to Lucius Malfoy during the event when Cornelius Fudge comes to take Hagrid to Azkaban and Lucius Malfoy hands over to Dumbledore his suspension letter. Dumbledore was able to sense Harry and Ron beneath the invisibility cloak by discreetly performing a non-verbal Human-presence-revealing Spell.
