Johnny bombs
If you don't already know, you make a johnny bomb by putting a condom over the end of a can of deodorant, spraying it full so it blows-up like a balloon, tying it off, spraying the outside with a little more spray and lighting it. Within a couple of seconds you get a wonderfully satisfying *THWUMP*, a lack of eyebrows and lots of astounded Year 8's.

If you happen to do it round the back of the science block, in full view of the Deputy Head covering a science class, you get a less-than-satisfying week of after-school detentions.
