Reminds me of the 2 A'level physics students who managed to set the school on fire. Debating due to water content whether paper would set alight in the microwave or not, they decided to try it in the microwave in the 6th form common room. Due to an utter lack of common sense, instead of trying it with a small piece of paper, they put in a whole pad. It set on fire.
Panicking, they took it out and quickly threw it in the bin. Which set on fire.
The best course of action at this point was to throw the bin out of the window and run away.
Unfortunately, the window was above a flat roof. Which set on fire!
Result? - several fire engines and a two week exclusion each!
I believe one of the lads went on to study at Cambridge!
