Ever wondered what happens when you combine 1,500 ping pong balls, warm water and liquid nitrogen? No, we haven't either. But we're glad somebody did, because the result is awesome.
This summer, Roy Lowry, an associate professor at Plymouth University in the UK tried a nice simple experiment. He poured liquified gas into a plastic bottle and closed it. This is a bad idea, Lowry warns the students in the video, because as the liquid turns into gas it will increase the pressure of the bottle. Then he put the bottle in a tank with warm water -- which is supposed to make the liquid turn into gas -- and filled the tank with 1,500 ping pong balls.
The result? Well, check the Youtube video to see yourself. It is well worth the build-up. You'll even be able to see a couple of replays is slow-mo.
