At each "node", there are permanent magnets that are "semi-loose": they are fixed in place, but they are at a unstable equilibrium. Once they receive an impact, they move, pushing the next ball, which goes to the next magnet, etc. > > > > > Liquid nitrogen explosion: > > http://www.youtube.com/watch?v=bdQZKxEVYQg > > We used to do that with dry ice and soda bottles.

I've never done it, but frequently heard about this recipe: With LN2, you can freeze vodka to the consistency of a jello, and then you can spread it on a slice of bread (use a dark rye bread for this).
