I don’t remember what it was, but it certainly wasn’t a firecracker. I don’t know where exactly my parents used to get them, but they used to get illegal fireworks (illegal in our state) by crossing over state lines, if I remember correctly. Neither me nor my parents remember what he set off, but it definitely wasn’t something wimpy like a firecracker.

Edit:

We lived in an area where you had more strict rulings on what is a legal firework to have and shoot off, so we definitely had some stuff that was definitely quite a bit stronger than what we could get in state.
