Patent the invention for safety! Issue a skateboard with every fire extinguisher!

That’s a great demonstration! I think the next time it snows, I may have to attempt this with a sled.

I’ve attended this year’s annual Faraday Lecture at Rutgers, where Prof Mark Croft does some beautiful demos (the physics show is intended for children between the ages 5 and 110!) which includes the human rocket demo. He actually does a pretty good circular motion holding the fire-extinguisher. You can see the video here.

Most of the other demos are listed here.

I know, but had not got around to it. But since you asked: Done. Cheers.
