| The World Famous Floating |
| This precision engineered trebuchet utilizes guillotine action and a plunging beam to maximize potential energy and a floating arm to convert that energy into projectile motion. In other words, this medieval contraption can fling a golf ball nearly the length of a football field! It's awesome! The kit is professionally engineered, designed and manufactured in the USA. Made with 100% hardwoods, each part is precision carved by computer controlled machinery for a guaranteed fit and accuracy. Note: This is a functional model intended for educational demonstrations of physics. It contains a fast moving arm and projectile that can cause injury if you make contact when firing. Use only under strict, competent adult supervision. |
