Potato cannon with rapid fuelling system on Kubota BX

My grandson Max and I had a great couple of days designing, building and testing this potato cannon. Max lives on mainland Canada so we don't get to see him that often but when he's here we usually do something interesting.  Lately Max is into drone flying and he and his dad got me into it too. So you will be seeing some drone videos in the not too distant future.
