Why does the coin placed at the bottom of the container appers to be raised when the container is filled slowly with water?

What happens when you hit the coin at the bottom?
Friction is a sticky force that appears when 2 objects rub against each other. If you push or pull slowly friction helps pull or push the tower along with the bottom coin. If you push or pull quickly, the coins still rub, but the friction force doesn't have time to get the stack moving. So the coin shoots out without pulling the tower with it.
