Not just for the bathtub admiral.
This intriguing little steam boat is agood opportunity to understand thephysical principle of the pulsed motor.It is not a speed boat, nor is it up to therigours of the open ocean. The keyparts of the motor, which does verynicely without pistons, valves orwheels, are a brass coil and a tea candle.In order to prime it, the coil is filledwith water with the aid of the pipette.When the tea candle is ignited part ofthe water in the coil boils, turning itpromptly into steam and expelling it.That creates a vacuum in the coil,which sucks in a fresh charge of water.Since the expulsion of the water isstronger than the subsequent suckingin of fresh water, the boat movesslowly, but steadily forward. The boat ismade of cork, which floats better and ispropelled a tiny bit faster. The pulsedmotor can be rotated to change thedirection of travel. The boat is made inBaden-Wuerttemberg.
the steam boat is not suited for children under 3 years of age because of the danger of choking on the smaller parts.
