when i was at my friends house, I would try and use a plastic grocery bag as a parachute. Don't worry, I only jumped off their couch. Unsuccessfully floating.
I am still a kid, but i once filled a closed ketchup bottle with ethanol alcohol and i was using it to spray out little puddles to burn, but the entire bottle caught on fire in my hands. I'm lucky i don't look like Anikin Skywalker.
as a baby, i was in a cot and far away from me was a small bowl with nivea cream. my mother do not know how i reached it, but i smeared all the cream over me. after my mother did not managed it to clean me my dad had to wash me with granulared soap.
