quote:Originally posted by robbins48There was an independent inventor/scientist on one of the science channel or discovery channel programs. He had invented a plaster-like substance that was extremely heat resistant. He spread it all over a football helmet, let it set up, put on the helmet, had an assistant apply heat from a torch (oxy-acetylene or the like) to the substance to demonstrate that it was not a heat conductor. Does anyone out there remember this? It may have an application for something I'm working on.
