— Description

The Bubble-Head Charm (incantation unknown) was a charm that produced a bubble around the head of the caster, giving them a continuous supply of oxygen, allowing them to breathe where they could not otherwise.

It was 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

An individual with a bubble around their head

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.

History

During the 1989–1990 school year at Hogwarts School of Witchcraft and Wizardry, Professor Filius Flitwick taught his sixth-years how to cast this particular charm in Charms class.

Known uses

"Harry looked up and saw Cedric swimming toward them. There was an enormous bubble around his head, which made his features look oddly wide and stretched."

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.
