It 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
- 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.
- 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.
