Surface tension

If the world didn't really have surface tension, there also wouldn't be hydrogen bonding; which is what makes liquid, liquid.

Water and all other liquids would be gases and because all living creatures need water to survive there would be no life on earth. Even if water was still water we need surface tension in our bodies to keep the billions of cells in our body alive. If surface tension wasn't in our body all the acids, blood, saliva, yes even pee and every other liquid in our body would mix together, in turn, we would die.
