This was one of several projects I built last week for a group of elementary age students. They had a ton of fun building different planes to launch from this ballista. It's always interesting to see what kids come up with.

The bow used is a 40lb PVC bow using an ingenious design presented in this video: youtu.be/rmxn-nPNhY8
