The standard Blower, manufactured by Ian Stewart and Mac McClintick. Built on a wooden base frame, it was primarily constructed from used tins; 2 cocoa tins, 5 Klim tins, 8 butter tins, 1 biscuit tin, and 2 New Zealand chocolate tins. This advanced form of the device works by placing burning embers into the tin fire-box underneath the Blower, and then turning a handle connected to a series of gears and a fan which drives the heat into the Blower, heating anything from coffee to porridge. Turn the handle slowly and the meal simmers, turn it fast and the device is transformed into a miniature blast furnace which will bring substances to the boil almost in an instant. It took Stewart and McClintick four hours to make each Blower, and it was sold at the price of 80 cigarettes.
