as a kid, stuffed co2 cartridges with safety match heads.

progressed to co2 cartridges with fast burning pistol powder, (burried it half way into a eucalyptus tree.

made a pipe bomb out of i nch galvanized pipe, greased threads and threaded caps - launched the cap across the canyon.

Popped a half full can of starter fluid into a burn barrell - kind of tuff on the barrel.

Demolition asistant to company chemical/biological/radiological specialist, then the fun began - taught basic demolition skills and got to play with plastic explosive to cut steel, flipped an armored personal carrier, (previously trashed and relagated to the demo range), stuffed a 40 pound cratering charge under one side and flipped it over on its back. Once on its back, we stood a shapped charge on a wood box and blew a 8 inch hole through the APC tread, the engine block under it and the tread on the other side, WHOAAA

Then sat a 45 pound shapped charge on top of a 6 foot 6x6 railroad tie. Blew it into toothpicks and still punched a 8 inch hole in the ground.

But, to the OP's point, one of the most impressive demonstrations i ever saw was a gallon of gas in a milk carton touched off by a pencil sized military cap.

Impresivo... Gas deserves a bit of respect.
