[spam][ot][rambling][crazy] Build a Bomb Out Of Water was: Spaceship

[jim bell]

Use a hollow steel ball with a threaded steel  plug.   Immerse in water to fill.  Thread plug, close tightly.   Immerse in liquid nitrogen behind a strong shield.  Water will shortly freeze, but cannot expand.  Eventually, the container will explode due to increased pressure.
