How did each of the competitors breathe underwater in Harry Potter and Goblet Fire?

You're likely referring to the Triwizard Tournament's second task , where the competitors had to rescue a hostage from the bottom of the lake.

Her er hvordan konkurrentene pustet under vann:

* Harry Potter: Han brukte gjeller levert av Dobby , husnissen. These gills were magical and allowed him to breathe underwater.

* Cedric Diggory: Han brukte en gillyweed , a magical plant that allows the user to breathe underwater.

* Viktor Krum: Han brukte en gillyweed også, antagelig. Selv om det ikke er eksplisitt oppgitt, er det den mest logiske forklaringen gitt at det er standardløsningen for å puste under vann i trollmannsverdenen.

* Fleur Delacour: Hun brukte også gillyweed , akkurat som Cedric og Krum.

Interestingly, the Triwizard Tournament rules did not specify how the competitors should achieve underwater breathing. It was up to the contestants to figure out a way to achieve it, leading to various solutions within the wizarding world.
