you’d be surprized how much punch even a tiny one can pack.
try this, take a small firecracker and put it on top of a bottle, set it off.. it’ll scorch a little off the wrapper, that’s about it.
now put it inside the bottle (and get away) bottle will explode. there’s a big difference between setting off an explosive and tamping/ confining it.
this guy prolly had his hand closed around a firecracker.
I agree. There is a lot of energy even in small firecrackers. When they are set off in the open air that energy works on the atmosphere an can expand and disipate quickly. At a rate of approxamately a cube root over distance.
But if it is contained that engery is going to work on what is containing it, in this case his hand.
On the flipside, that’s what make firecrackers and soup cans so much fun.
I had a good friend of mine have a Black Cat go off between his fingers. The result was a blood blister on his index finger and thumb. Granted, it wasn't confined, but that pic has all the skin stripped off the guy's fingers. Given that the hand is far from airtight, I don't see how regular firecracker does that much damage. I've set off firecrackers in a bottle (2 liter plastic bottle), and so long as you don't cap it the gases will escape and the bottle stays intact. Even confined that much damage has gotta be at least an M80.
