[Photo] From Swiss Army knife to Swiss army furnace

Designer Ryan Cavenagh, perhaps enamored of the red Swiss flag logo on the Swiss Army knife, designed the "Swiss Army Stove" during his sophomore year of college. This "military furnace" is mainly made of aluminum alloy, small and portable. It uses denatured alcohol as fuel, although it is small, it can quickly boil a pot of water, filled with alcohol can burn for more than an hour.
