After the large successes of
Rubber Band Engineer  and 
Duct Tape Engineer:  we lastly take away the boundaries of a single class and let writer Lance Akiyama create twenty devious weapons of yard warfare.

These simple mini-ballistas are constructed from PVC, soda bottles, rubber bands, hairspray cans, and anything you might find in the junk drawer. They can easily launch marshmallows, poker chips, tennis balls, sponges, and much more. Get creative and have fun setting up your own booby traps with these DIY gadgets!

This e-book is designed for adults, but it's also great fun for children and teens. The activities range from simple shooters that even beginner crafters can easily construct to more intricate projects like the Slide Action Rubber Band Gun, A Wrist-Mounted Crossbow, and a Mini Ballista hidden in a Desk Drawer Booby Trap.
