Gee, Gregg, I hope you don't get expelled for making bombs!

I had two students "experimenting" with Draino and aluminum (aluminium) foil for a science fair several years ago. Now that was interesting. But the best explosion I have personally experienced was when the 3 gallons of black powder a neighbor (who made fireworks professionally) was mixing in a ball mill blew up and shattered the windows in his house. I was there trying to get a client a job. He only lasted two days and then quit!

The neighbor used to tell me about really interesting combinations that are quite powerful - you wouldn't want to mix enough to fill a film container.

BTW, does anyone know the ingredients of the white capsules that were in WWll gas masks? But that's another story!
