Electric Shock
I used a similar idea when i was at school all i used was any old transformer connected a battery to the output terminals and added a switch, managed to get about 10 people in the class to hold hands and the end of the line grabbed a wire each on the mains side, flicked the switch and hey presto everyone in the line got a belt of it.
I never used a relay just the battery a switch and the transformer.
