Ping Pong Ball

Your last ping pong ball falls down into a narrow pipe embedded in concrete one foot deep. How can you get it out undamaged if all you have is your tennis paddle, your your shoe-laces, keys, wallet and a plastic water bottle, which does not fit into the pipe?

Using the plastic bottle, pour water into the pipe so that the ball will rise up.
