Kuhu Creations Supreme Practical Science Learning Water Toy. Steam powered boat, runs on candle, fuel flame. Description: Scientific Water Toy Steamer, Early Age Education Toy, Tin Boat – Length 12cm, Width 6cm, Height 3cm (Approx) Function: How does it work? When water is boiled in the coil, steam expands. This takes the water out of the tube. Feedback propels the boat. As the steam continues to expand, it encounters the section of tubing that is filled with water. This tubing cools, and the steam condenses back into water. This causes a vacuum to build up, which draws more water back into the tube. You would expect that the water going back into the tubing would cause the boat to go backwards. Although, The water doesn’t travel far enough before it hits the end of the tube (two streams of water in the two tubes meet each other in the coil). Any motion due to water being sucked into the tube is reversed by the water hitting the front of the tube (coil) and propels the boat forward again. As you’ve noticed when you place your finger near the tube, it’s back and forth water movement is quite fast, and a comparatively heavy boat doesn’t really move backwards. These are made in India from tin plated steel on a hand operated press. hand painted. They make a wonderfully loud “put-put-putt” sound as steam surrounds a bathtub, swimming pool or pond.
