Little Pump + Marble Machine // Light Base
This unique combination includes the Boehm Stirling Little Pump, their number one selling, and perhaps most charming, Stirling engine. Once assembled, it can generate more than enough power for the Marble Machine. This eye-catching curiosity for the young and old features 8 marbles that travel down a tornado loop. It's the perfect way to marvel at mechanical motion.
