Are you someone who enjoys learning how each piece works together perfectly to make a machine work? Build your own working model of a 19th century locomotive, tractor or zeppelin with this extraordinary steampunk DIY kit. Beautifully designed with an eye for detail, the wooden pieces are easily popped out from sheets of pre-cut plywood and can be assembled without nails or glue. Instead of steam, the models are powered by a rubber band, but the working of its engine, including an asynchronously operating piston and valve mechanism, are clearly visible. There is even a retractable ladder under the cabin doors. After it's assembled, you can have fun watching it go chugging across the floor or desktop, or simply put it out on display and enjoy a sense of pride and accomplishment in having made it yourself.
