I love hearing about other peoples school pranks.
When it comes to my last day next year, a friend and I plan to follow in the footsteps of a family member, and create a small contact explosive mix. It's stable when wet, but when it dries, it pops as soon as something touches it. It doesn't "explode" as such, but it bangs and sends up a small puff of purple powder. It's going to be painted on door handles, ash trays (if we find any
), floors, tables and of course...toilet seats.
It's not dangerous, but it will probably be the best prank of my life.
