This Little technical miracle work is described as "Einsteins trinking duck", because it is deliverd Albert Einstein had one trinking duck on his desk in his summerhouse in Caputh by Potsdam.
You must dip him only once in the glass of water and then he moves often for days/ weeks, without any supply energy - almost like an "Perpetuum Mobile". He takes his energy for his permanent movement of the air he stands. This little heatpower-machine has his function from the variable game of heat and cold. The Liquid in the stomach of the bird takes heatenergy of the air all the time. Because of the ability to take energy the Liquid extends and climbs to the top. The cool head assists the climbing Liquid trough the resulted low pressure. Through the becoming predominant the bird begins to drink. While dipping of the beak in to the glass the liquid of the head turns back to the stomache and the game starts once more.
