What is this stuff?

The pellets in the neckband were 1/16 of the volume of the space they were to fill. But after the first day, they swelled so much, it looked like a plump sausage. I was surprised. Um, Steve. Beforet use, you first soak the neckerchief in water for an hour to prime it. What is this stuff inside? It seemed to help a little when worn at the base of the neck, but after swelling, it didn't retain a lot of water. I kept three in rotation in a Zip-Lok bag with ice, wearing one, and when it no longer felt cool, rotating it with a cool one. Too bad she didn't explain how they work to you before you tried it. (How does it feel, sawing with the chainsaw and then being surprised by the noise it makes when you take it back to the dealer and they fill it with gas and start if for you, hmm? I must say, the best part was the dripping of the whole thing down my front and back and the evaporative cooling from that, but the cool gel was good, too. Is there a site that explains the chemical/physics aspect of "this stuff"? http://soldiersangels.org/uploads/CoolScarvesHowTo.pdf -- Just getting back after a farkin' virus ate my computer. I'm still without any email or usenet archives. sigh |
