- |It's called the Leidenfrost effect. The idea is, the outer layer blows

- I'm beginning to think that this stuff is so stable that you could use
- it as a food additive. Plop, plop, fizz, fizz, where is the kaboom it
- gives.
-
- Is antimatter too stable to be used as a propellent? Would we have to
- work hard just to get sufficient annihilations to do useful work?
