Modern Steam-powered Engine Construction
A modern version of the Hero engine can be created by obtaining a copper toilet tank float. Holes can be drilled into either side of the tank float. Copper tubing can be wound through the holes so that they are projecting from either side of the tank float and then soldered into place. Make sure that the drill bit and diameter of the copper tubing used are equivalent.
Fill the tank float with water and suspend the tank float from a string. Use a propane torch to apply heat to the bottom of the tank float. Steam will begin to form and as it exits through the copper tubing the tank float will begin to rotate.
Be sure to wear eye protection and follow school safety guidelines.
