I recently stumbled upon this marvelous photo documentation of the classic Box Monster booby trap.
The Monster is simply constructed from using a coat hanger, a shirt, a box for the head to draw a face on, mounted hooks and plenty of string. The photos show how the trap works and gives an idea what the poor victim is in store for,
The original trap I made in the late 80’s was set up inside a Wardrobe, using the same mechanism and the clothes rail inside instead of hooks.
Not for the feint of heart, but do try and copy this and give it a go if you know of somebody to prank. Hahaha.
