I always enjoy building things with/for my kids. So in 2013 I built a catapult game for the Scout Show. Full Details here: http://familab.org/blog/2013/04/building-catapults-for-the-central-florida-scout-show/
After seeing Jammie's Monster in a box at the Tamp Bay Mini Maker Faire, I had to build my own.
