I warned him! Lol.

Back when my youngest stepson was about 8-9 years old, he and his older brother were spending the weekend at their dads house. He got the bright idea to take some bullets apart and dump the powder into a can so he could see what it looked like when he dropped a match into the can.
He ended up without any eyelashes and eyebrows and a burn across half of his face. Luckily he healed up without any scars.

And alcohol wasn't involved...just young and stupid as most of us were.
