HERO’S ENGINE 1372-b
Flask form. Demonstrates the principle of the steam engine and jet propulsion.
When a small amount of water is heated in the flask, the steam produced is ejected
from holes in the jet assembly, causing the flask to rotate. Consists of a 250ml
flask suspended from a chain with swivel attachment, rubber stopper, and jet
assembly.
