This reminds me of a QO answer way back.
In detention for being cheeky to the German teacher. She foolishly left me alone. She liked to make herself a cup of coffee during lessons and had a kettle on the bench at the side of the room. Not knowing how long she'd be I quickly set to work on her kettle.Opening the plug I separated a few wires from the live and neutral cores and twisted them together.All that remained to be done was to switch the socket off and the kettle on; my trap was prepared. I put the word around so the incoming class knew the score. Apparently everyone watched with baited breath as she wandered over and clicked the switch. The resulting bang,flash and black smoke were, I'm told, rather good.
