Somehow we acquired firecrackers the size of coke cans
I'm not even exaggerating which is the scary part.
They're just a normal firecracker, unless they were made by someone illegaly. Anything larger than a firecracker is federally illegal, all those m80s you see at stores and stuff are super stuffty and just in huge cardboard tubes.
This guy at a fireworks store by me used to sell fireworks to people that lived in PA which is illegal. He also had a mortar and pestle at the register and was making flashpowder for m80s he was selling. I bought a few once and went back later and asked about them and he said "I don't do that kind of stuff it's illegal"
