We went to the festival today. Didn't get anything. Though there were lots of things that I would liked to have had. I did see some of those neck coolers that some of us here make. I asked someone here a couple years ago about how much would you sell one for and I think someone said around $5.00. Well there they were selling for $14.00. They said that once you get them to swell you can put them in the microwave for 30 secs. to 1 min. and some stay warm any where from 45 min. to 1 hr. Has anyone heard of putting this in the microwave too?
