Rick Andreasen asks about matchless fires
One of the neatest demos I ever saw used Calcium Carbide and tap water.
When wet the carbide gives off acetelyne (I think) gas which can be started
on fire with a small spark. This, I'm told, is how old miners lamps worked.
The neatest thing is the flames increase as you add water, blowing the minds
of the observing scouts, who are used to water putting fires OUT.
This can be played up if you happen to be near a "gravel" drive that has
been prepared in advance. The leader strides to the edge of the road,
scoops up some ordinary looking rocks, and. . .poof.
I obtained my calcium carbide from a school chemistry teacher, a chemical
supply house might also be able to help.
