I dunno if you remember Hopper Poppers?
I had one when I was eleven or twelve. They were made of rubber, almost like half a rubber ball. You'd turn them inside out and put them on the floor and they'd pop up into the air. One day I was messing about and I licked it and stuck it to my forehead, making my brother laugh. It was on there for ages. When I took it off the suction had burst a blood vessel and I had a huge purple bruise in the middle of my forehead for a week.

School was fun. I was an odd child.

That sounds exactly like the sort of thing my brother would have done. He once stuck a Lego mans hand up his nose... we never did see it again!!?
