My 9 year old grandson and I built the 'Viking Cayapault'. We made it a learning experience as I taught him how to lash the parts together and we had a lengthy discussion of how the Vikings lived and probably visited Nort America before Columbus. While we had to modify the catapault desing to make it actually work, we had a grat time and both look forward to building the next catapault when he comes to visit next.
