"These contraband items are useful for clearing a room."
— Description[src]

A Dungbomb was a magical stink bomb that gave off a putrid odour.[2] Dungbombs were invented in the 1800s by Alberic Grunnion.[1] When handled, Dungbombs left a person's hands dirty. They were sold at Gambol and Japes Wizarding Joke Shop, priced at one Sickle and twenty-one Knuts each.[1]

Known Uses

In or around the 1910s, Leta Lestrange, whilst a student at Hogwarts School of Witchcraft and Wizardry, let off a Dungbom under the desk of Prendergast, a Hogwarts employee, so she could join her friend Newton Scamander in detention.[6]

Despite (or perhaps due to) Filch's dislike of them, students use them at school, most notably in 1996 in the aftermath of Fred and George Weasley's departure from Hogwarts.[7] The Weasley twins once set a Dungbomb off under their Auntie Muriel's chair, leading her to never visit again, and she subsequently wrote them out of her will. In their first year at Hogwarts, the twins set off a Dungbomb and incurred Filch's wrath. Sent to his office, they discovered the Marauder's Map and George caused a distraction by dropping a second Dungbomb so that Fred could nick the map.[2]

In 1995, Nymphadora Tonks also taught Ginny Weasley to test a door for an Imperturbable Charm, by checking if Dungbombs bounced away after being flicked at the door in question.[8] Later that same year, Filch accused Harry Potter of using an owl to order Dungbombs, when he was actually sending a secret letter to Sirius Black, and Harry truthfully denied it, with the backing of Cho Chang.[9]

In 1996, as the tyranny of Dolores Umbridge reached a new level with her becoming Headmistress, the students of Hogwarts revolted en masse, and Dungbombs and Stink Pellets were dropped in the halls with such frequency that it became the new fashion for students to use the Bubble-Head Charm just to ensure that they had a supply of fresh, clean air.[7]

Ron Weasley once expressed his fondness for dungbombs by writing "Dungbombs rule" in Harry Potter's copy of Fantastic Beasts and Where to Find Them by Newt Scamander.[3]

Students are constantly reminded that dungbombs are banned items at Hogwarts School of Witchcraft and Wizardry by Dumbledore, though only at the request of Filch.
