Serious question, I have no idea. Is there an established tradition, sequence of events, rule?
I just asked some kids, and they said they’d come later and secretly do some trick on me, but they didn’t seem too sure about it either.
This in Europe btw.
When I was a kid it was shaving cream. Take a can, put a needle in the nozzle, then melt the nozzle with a cigarette lighter. Once it’s cooled pull the pin out so you have a pinhole nozzle. It’ll spray the shaving cream ten feet or more.
I honestly forget how I learned that trick…
