My girl just got back from her trip to Poland and bought me some interesting gifts. She knows that I'm into "strange" things and worries about me when I wonder around the state park in the middle of the winter. So she got me a special heat pack. Now I'm used to typical chemical heat packs. You break it, shake it around and it gives off heat. The thing she brought me is way different. It's a metal case that is lined with some kind of fireproof material. All this is sealed in hardcore stainless stell shell and outside is covered with felt like material. You take a stick of compressed coal and set it on fire. You put it inside the case and you have a really nice heater. You can set the stick on fire from two sides for double heat or from one side for steady warmth. Very, very interesting. <br><br>You can see a pic here:<br>https://ssl.kundenserver.de/s25752635.einsundeinsshop.de/sess/utn153dcf9bff5b747/shopdata/0100_1.Hilfe=2C+Hygiene=2C+Insekten-=2C+Sonnenschutz/0120_1.Hilfe=2C+=DCberleben/images/he082_298x354.jpg
