Find your Gift on UniqueWorld Shop: Bohm Stirling HB28 Mini Hot Air Engine

The Stirling engine is an engineering marvel based on the cyclic compression of air, and in the case of the gorgeous Bohm Big Bridge Stirling Engine, heat. Simply light the candles and watch the engine work harder and harder as the gases expand and contract. You can even attach extra accessories like the Greek Windmill, which function perfectly under the Big Bridge’s natural power.

You can buy this engine as a kit, perfect for the tinkerer, or pre-assembled and ready to use. It’s a truly unique and wonderful gift idea.
