Go blow off your hands
But In all seriousness have a fun time, don't hurt yourselves though, a couple of days ago me and some friends got the idea of going to a lake (keep in mind we live in Washington, so it's cold as all holy hell) and as i got in the lake I freaked out cause it was REALLY hot outside but REALLLLLY cold in the water, then one of my asshole friends got the idea of throwing a hand whole of firecrackers into the lake, he intended to throw them far away but he was under a tree.... and i was also just barely under that tree, in the water, where it would take forever to run away... hold story short, i got a burn mark on my back now and he was a black eye
Try to be safe, oh fuck that, blow your hands off.
