Don't mess around with electricity.

In high school auto shop it used to be a thing to attach a used condenser to a plug wire, ground the case, and crank the engine, and then leave the condenser lying around for some hapless person to pick up - zap! You only picked one of those up one time before you learned that an unattended condenser = possible land mine

Capacitor maybe? We had pranksters at work that would rig a charged capacitor to a tool on the shop table knowing guys come in and fingerfuck things left around.

A condenser is a capacitor, but it was called a condenser - ie: replace the points and condenser. Electronic ignitions got rid of that task.
