Little Pump + Marble Machine // Light Base
Patented in 1816 by Robert Stirling, the hot air engine or Stirling engine is based on a simple principle: A burner filled with fuel heats the air inside a cylinder and thereby purveys energy to the motor that activates through piecing of the flywheels.
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.
