        Would you elaborate on why the mold is put in the refrigerator?
        If you can cut, drill, saw, hit things and swear a lot, you're well on the way to building a working model sub.

            The Plasticine backing clay is too prone to clinging at room temperature and sticks to the RTV flange portion of the tool half. Lowering its temperature permits easy removal from the flange without having to resort to scraping and a lacquer wash to remove sticking clay.

                An article I saw once said that Play-doh was originally a product used for removing coal dust from wallpaper called Kutol. Post WW2 people switched to gas heating, and the market dwindled for Kutol, however the maker recognised that the original product was often used for recreation, and rebranded it as product for play rather than utility.
