Hmmm, in my A level chemistry class we were a bit of a handful. We made plastic slime one lesson (it was supposed to teach us about the properties of polymers or somthing). It was a bit dull until somone discovered the floursecent dyes, whereupon we coloured our slime and threw it out of the window (as you do). When we were stopped at doing this we threw it at the ceiling insted.
