I thought I was exaggerating about those polymer granules, and I was actually totally minimizing their ability to absorb water and swell. I said they would swell to 50x their original size, and it’s really 400x!! They actually get cooler as they evaporate, and will keep cool for 2 or 3 days! The neck coolers sound like a really good thing for the soldiers, so I’m going to make a BUNCH more.

Where does one obtain these polymer granules? Clearly I need to be encased in them.
