- "The Bubble-Head Charm is used to allow a person to breathe underwater. An enormous bubble appears around the head of the person casting the spell, which makes their features look oddly wide and stretched."
The charm causes a protective bubble to form about the caster's head, described to look like upside-down fish bowls; this bubble may allow for underwater exploration or to avoid nasty smells, although wizards with bad breath have reported problems after the first thirty minutes.
|Cedric Diggory||24 February, 1995||Used during the Second Task of the Triwizard Tournament to enable them to breathe underwater.|
|Hogwarts students||1996||Students also used this spell after the departure of Fred and George Weasley, when it became fashion to throw Dungbombs and Stink Pellets in the corridors of Hogwarts.|
Behind the scenes
- In the films, the charm creates a bubble around the mouth and nose, similar to an oxygen mask, not the entire head.
- It's unclear why Harry Potter was unable to find information on this spell while researching for the second task. It is possible that the spell was a relatively new invention not covered in many books as of 1995, or that the spell was not commonly used for breathing underwater, but for other purposes. It was also said that Harry searched for a spell "that would allow human to survive without oxygen", rather than for some form of oxygen supply.
