Each of these launchers are made from PVC, soda bottles, rubber bands, hairspray cans, and anything you might find in the junk drawer, and are capable of firing marshmallows, poker chips, tennis balls, sponges, and plenty more.
This book is written for adults, but kids and teens can get in on the fun, too. Projects range from simple shooters to be built by novice crafters, to the more complicated Slide Action Rubber Band Gun, A Wrist-Mounted Crossbow, and even a Desk Drawer Booby Trap.
