THERMITE!!!
Or, just to be dull, powering something using aluminium (pert of a Coke can?) and iron (a nail) stuck in a lemon. But that's booooooooooooring.

I went to a public lecture at Warwick university about 40 years ago, given by an incredibly old eccentric scientist who was an expert on explosives. It was a very entertaining lecture with lots of bright flashes and loud bangs, but the thing that left a lasting impression on me came right at the end of the lecture ...
I was sat in the back row of the steeply sloping theatre. The mad scientist had just announced that the last explosion would be the loudest of the lot. I can't remember what he was trying to do, but I know that he put a coin on top of whatever it was that he was blowing up. Anyway, he lit the fuse and stood back about 6 feet. I thought that perhaps he was standing a bit close. The people in the first few rows were cringeing in apprehension ...
Suddenly, there was an almighty BANG!!! and I saw a spinning object hurtling up towards my face. I instinctively ducked, a reaction which probably saved my teeth as a hot, bent coin slammed into the wall directly behind me.
I heard an embarrassed voice from the front say "Now that wasn't supposed to happen!"

Not a problem! Just stress repeatedly to the teachers that only free-range eggs will be used, and with any luck they'll be so distracted by this they'll forget to worry about the boiling water

That was my favourite experiment at school.
They'd already banned the teachers from using a thunderflash to demonstrate the speed of sound so I think I was lucky to see this one.I expect they can only show a video about it these days.
