Build your own Putt Putt Boat

Build your own Boat
A putt-putt boat is a toy with a very simple steam engine without moving parts, powered by a candle or oil burner. Its name comes from the noise this boat makes. It is powered by a very simple heat engine. When we heat the engine which is connected with two exhaust pipes using a candle, water starts to become steam and this steam pushes exhaust tube water forward. In this process, steam gets condensed and creates a vacuum inside the tube due to which water from outside gets pull inside the tube which produces the sound putt. The repeated cycle of the above procedure moves the boats forward and gives us the impression of the engine running with the sound of putt-putt.  Note that in putt-putt boats with two exhaust tubes, the water is expelled from both tubes during the first phase of the cycle, and drawn in from both tubes during the second phase of the cycle. The water does not circulate in through one tube and out through the other.
