When I was in high school, there was a short-term underground 'trend' that involved transformers, batteries, and wires. Someone would connect a battery to a transformer and then hold one of the wire leads. He'd then recruit as many people as possible to form a human chain, hand to hand. The last person would grab the other lead and the entire group of people held on as long as they could take it. Occasionally, the group was too big or the battery too weak to feel much, but other times the group size, and/or the battery/transformer combination was just right to cause quite a jolt.
I think the administration put a stop to that one.
