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.


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[1].

Known usesEdit

Behind the scenesEdit


Fleur Delacour using the Bubble-Head Charm during the Second Task

  • 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.
