That's nothing. I know a couple of guys who were out drinking. The owner of the van had dynomite (early 80s). He stopped on a dirt road to take a leak and the drunk that was with him bit into one of the soft dynomite sticks thinking it was a burrito or something. It didn't blow up but it nearly killed him.
"Mamma mia, thatsa some spicy pepperoni!"
Dynamite cannot blow up by hitting it, biting into it etc. It takes a powerful blow, such as a blasting cap explosion to set it off. Swallowing it however won't do you much good because it is mainly nitro and sawdust.
Back when I was a kid, there was a firework similar to crackerballs. I think we called them torpedos. They were tin foil colored and about the size of a cherry bomb. They were set off by throwing them against something.
This was in the forties, when fireworks could be bought anywhere, even toy stores, especially toy stores.
A mildly retarded neighbor thought they were candy kisses and bit into one. Blew his whole lower jaw off. We had a reminder to be careful with fireworks everytime we saw him.
The dynamite guys would get sick (headaches, etc.) from absorbing the nitroglycerin while cutting the charges to the needed sizes.
