Learning physics by launching things
We’re building trebuchets in northern Berkshire County: desktop models that kids build and launch in free workshops, and a community-built machine at least 10 feet tall that can throw a pumpkin hundreds of feet, which we aim to have ready by September 2027. It’s all free and run by volunteers.
Start small, build big
Kids start with a desktop trebuchet they build, test and take home, changing one thing at a time to see what happens. Meanwhile we build bigger machines: a “Big Yard” (3–4 ft) trebuchet in early 2027, then one at least 10 feet tall for free community launch events, which we aim to have ready by September 2027.
