Next thing some inventive genius will design and make an adapter for the nail gun so they can shoot bullets!!!
When I was in 7th grade they took us on a tour of the state police training facility which had a museum of all the confiscated homemade weapons. Wow was that dangerous information. Showing a 12 year old how to make a rat trap 12 gauge shotgun and a zip gun. Never made any of them, but it would be easy.
