About This Design
It Takes A Lot Of Work To Exist (Thermodynamics) Pacifier
No need to be a physics major or physicist to enjoy any of these gifts featuring the Carnot heat engine, along with the wry truism saying "It Takes A Lot Of Work To Exist 24 Hours A Day, 7 Days Per Week, 365 Days Per Year". Specifically, these gifts feature the second law of thermodynamics. Since any thermodynamic engine requires such a temperature difference, it follows that useful work cannot be derived from an isolated system in equilibrium; there must always be an external energy source and a cold sink. Educational physics attitude gifts for all who work in the thermodynamic sense of the word!

I have ordered the pacifiers several times and they never disappoint. They're a little pricey but I dont mind every now and then. The design looked good
