I'm glad I had this idea when I was into model railways as a kid

Shorting the rails did spark a bit (cool, obviously) but no muscle clamping or throwing of children!

I didn't learn from it though I guess, many years later I lightly burned a toe touching it to my PC's motherboard.. really weird feeling when your muscle does something faster and more violently than you could ever make it do on purpose! Don't work on a computer on the floor with the case off without footwear! Impressively the computer didn't suffer any ill effect, once I'd got the power back on it booted up fine

I've also given myself a dead arm trying to unscrew a fridge lightbulb.. that someone had already removed allowing my finger to pop in and complete the circuit for a moment. Whoops

Earlier in life (after model railway, before kicking motherboards) I got a school detention for joining (starting?) a wave of kids charging capacitors and throwing them to each other with a "think fast!". All fun and games till someone throws one to the teacher

I don't play with electricity much anymore, my tinkering is limited to battery powered things or less
