Unlike most rubber band guns, the Arcus uses the energy from the rubber bands being shot out to rotate the barrels and continue the barrage. Grab the 3D models and directions on Instructables.
A while back, Tom Stanton built a cool working trebuchet, but even though it was much smaller than the ones used in battle, it still wasn’t exactly portable. So, Tom set about building a pint-size version that can be used like a slingshot. We’re thinking it would be perfect for flinging wadded up paper at officemates.
