(True dynamite is nitroglycerine that has been soaked into an absorbent material, such as sawdust or certain types of clay, which makes it a lot more stable. The higher the percentage of nitroglycerine, though, the more sensitive to shocks it will be. Modern dynamite usually consists of different explosives that's merely moulded into the traditional dynamite "stick" shape.)
