I remember when I was young I saw people emptying the water from their tanks using a flexible tube(without any pumps or other mechanical device). If I am not wrong, you first fill the tube with a little bit of water and make a U shape,then you close the 2 ends with your thumbs and put the tube in the tank and somehow it begins to suck the water out of the tank.
I'm curious to know what causes this? I thought of Bernoulli's principle/effect but I don't really understand the explanation on Wikipedia. Never learned anything about it in school either.
Can anyone explain this to me? In simple terms and/or with simple formulas please. Just wanted to know :D
