	Drinking Bird - a novel heat engine - £9.98 OUT OF STOCK - want an email when in stock?
	This is a classic toy. The Drinking bird swings taking regular sips of water until it runs out of water. The toy often runs for days at a time despite just using evaporation of water to power the device. A great demonstration of thermodynamics.
