If you’re just dying to cause some trouble at work, these models are the way to do it. They’d be perfect for cubicle wars. Each one doesn’t require much in the way of experience with models and you’ll only need a pair of scissors and some glue to put it together. The Trebuchet is the more complicated of the two, it’s also the one that will fling balls (they are included) the furthest. The Trebuchet will take 1 to 2 hours to assemble, but seems well worth it since it will fling the balls over 20 feet. It’s a working replica of the 13th Century trecbuchet and stands 26in tall.
The less complex would be the Catapult, which is based on the medieval styles used in the middle ages. It stands only 15 cm tall (which seems a bit small, but that’s what it says) and can fling a ball over 15 feet. You can also change the trajectory angle to add to the fun. The Catapult being the more compact version is also a bit cheaper, you can pick it up for $29.99. The trebuchet, can be purchased for $39.99, they are both for sale on Office Fun.
