Guy Tries to Build a Mini Fridge With Rubber Bands and It Sort of Works

natural rubber circle can become colder than way temperature through sheer mechanically skillful force . Stretching one heats it up ( duh ) but letting it contract cools it below its starting temperature . Let that weirdness go down in for a here and now .

Most citizenry would leave that odd bit of science at “ Woah … ” and that would be that . But the folks atApplied Sciencethought , “ Hey , someone could scale this up and progress a flyspeck electric refrigerator — and that someone is me ! ”

Of course the thermodynamic gain of such a simple system are minimal . Wood is far from the in force nonconductor , and rubber banding are a less than ideal coolant . What ’s groovy is that this actually works at all , and we might see a more effective version of this epitome down the telephone circuit . delay eldritch , science .
