Sometimes when you are sitting at your work bench you decide you need to clean up all the loose nuts lying around. This little tool is for putting those loose nuts where they belong.
1. get tape, allen wrench, two nuts that will fit on the allen wrench, and a ball point spring
2. put a little tape on the small end of the allen wrench
3. put a nut, then the spring then a nut on the long end of the wrench
4. pull back on the nut closest to the end of the long end of the wrench, aim and let fly
Range is about 10 meters. Don't shoot it at any living thing, it hurts.
