Stirling Motor HB26 Twin Bridge

Kids build models of plastic cars. Well, we do to. But we also build cool stuff that kids aren’t allowed to touch, like this sweet working model of a double cylinder ($300). Just apply heat and boom, the principles of propulsion are nicely illustrated. Hey, it wouldn’t be an adult toy if there weren’t some education involved.
