- I haven't heard of these "Glow Cubes", but the "EXIT" signs in
- commercial airliners are made this way -- I believe the plastic
- in that case is polyethylene, and the tritium is not so much
- "encapsulated" as the polyethylene's hydrogens are replace by
- tritium. I asked a friend in the airline industry if he could
- snag me a couple, but he could not.

- and pitchforks... :-)
