Clouds, bangs and balls

This amusing video shows what happens when a science teacher is set loose on a television sound stage

This science video is a lot of fun, although the scientific explanations are a bit sparse. Steve Spangler is a science populariser and this video captures him teaching the public a little about chemistry on The Ellen DeGeneres Show. In this amusing video, you'll see how Mr Spangler creates a cloud in a bottle, a huge fireball using powder and finally, an explosion using liquid nitrogen and 4000 ping pong balls:

My question: did Neil* clean up all those pingpong balls?

Steve Spangler has a really fun website designed for science teachers and kids of all ages, and he is on twitter @SteveSpangler (I must warn you that his website is absolutely dangerous!)

* Neil is the trusty assistant who is stuck cleaning up after explosions created for many of the PeriodicVideos' chemistry videos that I share on Friday mornings.
