Yeah, what will they come up with next?

So let me come up with a quiz and see if anyone can solve it?
A man is stuck in a stone cave. The only way to get out is if he gets a ping pong ball out of a steel pipe that is cemented 3 feet into the ground. He has nothing with him except a hairdryer and a basket ball. How does he get the pingpong ball?
