Who has watched "Into The Blue"?? Well since watching it I`ve always wondered if someone could actually breath directly off the cylinder pillar valve underwater and how on earth that Hottie Paul Walker got it right. So one sunny afternoon in South Africa I decided to jump in the pool and give it a go. Guess What: It does work!! Not extremely comfortable, but you could easily hide away from a bunch of bad guys on the surface using this method. :) Note: be careful of how wide you open up the air, could end up looking (and feeling) like an inflated balloon. LOL. PS This experiment was conducted in controlled conditions with help on stand by ;)
