I bought the instructions from the back pages of Popular Science. The stuff is so sensitive that it went off with a loud bang on the back porch when the front door blew shut! That was very cool stuff.
Also liked the exothermic reaction of glycerine and potassium permanganate. At first I thought it failed, so I tossed it in the HS lab trash. Big mistake! In a few minutes, the entire wastebasket was flaming. Great excitement, indeed.
Is that the same as the exploding mouse trap?
