Many years ago I took my small children to an Amusement Park. It was HOT! At one of the little kiosks, they has a strip of cloth at they claimed once it had been soaked in water would do a great job of keeping one cool. I bought one and stuck it in a paper cup full of cold water. At the end of about 30 minutes the cloth tube was swollen full and squishy. I put it around my neck and went “Ahhhhhhhhhhhh”. Over the years I have made many of these as gifts. People love them. It takes very little time to charge the crystals, but it takes over a week to completely dry out. They can be reused, again, and again and again. I usually carry a dry one in my purse or pocket. You never know when one might come in handy. So here is: “How to Make; a Water Charged Neck Cooler”.
