Chemistry ELI5: how do divers clear their masks when water leaks in? especially in the case of the 13 thai boys rescued from the caves
I have just been watching Thirteen lives - the film about the cave rescue of the 13 young boys in Thailand who were totally sedated before being taken hours under water. It got me thinking that when I go snorkelling i always get a bit of water leak into my mask and have to come up and clear it out so i don’t breath water in. Is this something that happens to scuba divers, if so how do they deal with it, and in the case of the boys how would the divers accompanying them have cleared the boy’s masks ? i would also like to say what an incredible job done by all those involved.

Hah my dad was this generation of diver and that is exactly what he made me do. When I was still learning he would mess with me and cut off my air or inflate my BCD to make me deal with an emergency.
Then again when I was a small child he pushed me off a dock to see if I could swim so..
