I've been working slowly on some more projects using Mott's plastic applesauce cups that look like barrel halves. Here are a couple of three-wheeled "tanks" just about ready to roll off the production line. The main body can lift off of the undercarriage and sits on dowel so it can turn. The larger back wheels are tops off of squeezy pouches of applesauce. The front wheels are wooden craft disks sandwiched between sawed off Dove ice cream bar sticks (the sacrifices we make for our craft!), with jewelry gears added for flavor. The tops and gun barrels are bits of craft pegs, plastic pen barrels, small dowels and other odds and ends. I'm not sure if these are done or if there is anything else I want to add, but they'll do for now.
