Now.. those bought me back to childhood...one day, my friend made a hot air balloon with a trash bag...(with no warning label that says may cause suffocation if put on head.), wax, gasoline and fire. It hit the roof of my friend’s house, but then it landed 5 miles away...we followed it on our bikes.
Dude, I completely forgot about the dry cleaning plastic bags with a little payload of Sterno in a metal bottle cap of some sort. Even back then those scared me. It was great seeing them go up, then you thought about the shit you’d be in if they came down in the wrong place.
