Tinker Crate is a subscription service that provides small, STEAM-themed building projects monthly in “Tinker Crates”. The Trebuchet kit is one of these projects, and it includes all the components to construct a miniature trebuchet and a “Tinkerzine” with information about trebuchet physics, historical facts, and the instructions for the kit. The trebuchet is built of laser-cut plywood and is sized to launch a ping-pong ball up to about ten feet. While constructing the kit is an easy way to develop spatial skills, the addition of historical and scientific information through the literature improves the educational value of the kit as a whole, giving kids the chance to learn more about trajectory and forces as applied to medieval siege weaponry. Tinker Crate offers a database for more DIY opportunities on the company website. Tinker Crate is a monthly subscription, but beyond that, it’s an opportunity for continual learning.

      • “I was really surprised how user friendly this kit was and the quality of the items that were included inside. We did have to use some items from around our home to complete all of the activities but they were pretty common items and were easily found. I like that my child had fun and also learned something.”
