Two Can Steam Engine.

A challenge among friends... Build a small engine in a couple hours using parts around the house... I came up with this little engine using two tin cans. 1- For the boiler and the top of can 2 for the flywheel. Some 1/4-20 shelving bolts gave the flywheel some weight. Designed to run off steam it is running on a couple pounds of air here. Since there is no safety valve the silicon tubing from the fill port to the piston is designed to pop off relieving any excess steam pressure. Just for fun... ;)
