You all wonder what man will sell in the name of science. I went to this art and craft show and walked in with my camera takeing photos and I noted a lot of people was nervous. Next thing I know this lady was demaning me what I was going to use the photos for. I told her I going to put it on the net at this site. WOOOO She went into a fix of some type. and say people do not want they work on the net for they work will be rob. Only the ones that give me permission I can post. Plus no camera was allow. I saw no signs and I was not hideing the camera. Plus what I saw most of it was not worth putting up anyway. I did buy some stuff before the woman came haveing a fix. I did not buy nothing else after. But I did walk over and ask this man if I can put his stuff on the net and he say yes. So here it is. "Right" you say " what is it?" It for relief from Astha and Allery. It is rock salt from the Himalays Mountians. That why the color is what it is. Rock salk from Louisiana is white. They cut out a place and put a light bulb in it and it put out neg. ions and give relief. Guess they did not wish this stuff to get to the medical field. have a good day and thanks for the comments
