Bubble-Head Charm

The Bubble-Head Charm (incantation unknown) is the most effective spell for breathing underwater or in any environment where fresh air is at a premium, allowing one a supply of oxygen.

Effects
It causes a protective bubble to form about the caster's head, like a helmet; 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.

Known uses



 * It was used by Cedric Diggory and Fleur Delacour during the Second Task of the Triwizard Tournament to enable them to breathe underwater.
 * Hogwarts School of Witchcraft and Wizardry students also used this spell in 1996 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



 * A similar full-body spell called Ebublio is seen in the Harry Potter video games.
 * In the films, the charm creates a bubble around the mouth and nose, similar to an oxygen mask, not the entire head.
