Today 3:36 pm
An IR beam detector that triggers the release of a spring loaded, barbed steel spike that goes right through the hand of whoever trips the circuit.
You could substitute a .22 caliber round that is fired by a solenoid through a short section of pipe, [instead of the spike].
There would need to be a 1 second delay to give the **** Headl's hand ample time to get centered under the trap.
