Aqua-Lung



Aqua-Lung is a brand of scuba diving gear in the Muggle world.

In Harry Potter
Harry Potter considered Summoning an Aqua Lung scuba diving suit from the nearest Muggle village to aid him in the second task of the Triwizard Tournement. Ron Weasley liked this idea, until Hermione Granger turned it down, due to the fact that they would have to risk Muggles seeing it flying across the countryside, which would break the International Statute of Wizarding Secrecy.
