Bob Coulston, a woodworker and contractor, has a wildly oversubscribed Kickstarter for a laser-cut plywood "shotgun" rubber-band gun that fires tons of rubber bands at once. There are a couple different kits, and both look like good fun.
The Sheriff shotgun kit is 14 pieces of laser cut plywood stacked and held together with binding bolts (no glue required) to form an awesome one of a kind 10 shot rubber band shotgun kit with three methods of firing.
The 3 modes of shooting:
* "Single Shot" - Pull the trigger to launch a single shot and pump the actuator back to reload the next rubber band
* "Rapid Fire" - Hold the trigger back while pumping the actuator rapidly to launch an arsenal of rubber bands that nothing can escape.
* "Shotgun Blast" - Pump the actuator until all rubber bands are at the top and then pull the trigger to fire a scattered blast of rubber bands that will knock over about anything.
