< PROTECT YOUR FACE WHILE USING >
It is powerfull and effectively tested in game.
This is the material you need for it:
An old fashioned Rat trap, two small screws, one longer screw and a 'screw eye' (excuse me for any language mistakes, I'm Dutch), old jeans or other strong cloth.
The tools I used:
Electric screw driver, small drill, scissors, pliers and spray paint
You also need some rope, tent pins and BB's to make it work... ;-)
Step 1: (optional) pre-drill holes
These two holes are made to make the trigger. You might also want to make two small holes on the opposite side.
Look at 2nd image to see the trigger system.
