CANDLE BOAT POP-POP-BOAT

This boat with its pulsar motor demonstrates physical principles and is wonderful to listen to when it is working. The heat of the candle turns the water in the boiler into steam which provides the drive for the boat. Water and steam throb through the piping keeping the boat in motion until the candle is burnt out.
Contents: prepared wooden pieces, sand paper, pulsar motor from metal, rubber tube, glue, candle, syringe to fill the motor with water.
From 10 years, develops understanding of physical properties.
