Pop Pop Boat
Manufacturer: Legler
Traditional tin toy Pop Pop Boat.
A pop-pop boat is a toy with a very simple heat engine without moving parts, powered by a candle or oil burner. It was patented in the UK in 1891, but may have precursors dating to 1880. The heat engine is a steam boiler. Water in it flashes into steam, which pushes the slugs of water in the exhaust pipes propelling the boat by a pulse of water. The name comes from the noise the boats make. Tin toy for ages 14 and over. Size approx. 13 x 6 cm
