A while ago i was watching a show where people were floating in a bubble, they were heading towards a sharp object and by hyperventilating they inflated the bubble, it lifted up and away from danger.
Now my mind went like : Wait a minute they are all inside the bubble breathing the air , so since the volume of gases would stay more or less the same the size of the bubble can not increase. Even worse by exhaling a lot the bubble would keep going down due to the fact the carbondioxide is heaver then oxygen.
After that i was like I am watching an animation where a platypus is a secret agent(Phineas and Ferb) and the bubble thing is the bit that bothered me >.<
Anyone else had moment like that
