1934 Wrist Ice Box

This is a miniature refrigerator that straps to the wrist. It encloses a pellet of dry ice which when evaporates, forms an invisible gas that lowers the temperature of the blood in the arteries of the person wearing it. This cooled blood is then carried to every part of the body making him feel cooler than the surroundings. Don't you just love 1930s inventions?
