Where do you get the crystals?
You can get them in the garden department of stores. Home Depot has it and probably Lowe's etc.
Their original use is to mix with soil for a potted plant. The crystals absorb the water and you don't have to water so often. The crystals also "release" the water slowly.
Once I got my cool tie wet the first time, it lasted for hours. The puffiness never went down all the way, but is still good at absorbing water and staying cool. Ice water is the best!
