This showed up on my feed today and seems pretty interesting. Anyone tried this before? Once I can find enough bottles I'll try to build one for my side barn door opening and see if I can make a version that is stowable.

So first you need some breeze. Secondly, you need humidity low enough that sweat will actually evaporate.
