Paper Trebuchet

October 8, 2011

No kitties were harmed during the production of this video. The trebuchet requires a bit more tuning. I need to lengthen the sling and adjust the ratio of projectile mass to counterweight mass. The projectile is a wadded up ball of aluminum foil, whose mass is less than one gram. The counterweight basket is holding 77 grams of quarters, ball bearings and other tchotchke. I’ll post more on this including some slow motion footage once the siege engine is better adjusted. I’m guessing a 20-30 foot range will be possible with this machine.

This project is a warm up in preparation for building something a bit (or more than a bit) larger at school. Look out pumpkins…
