1. place a small amount of water in the empty can (a couple of teaspoons will do)
2. Heat the can over a stove until the water boils (tongs are quite useful here).
3. Immediately plunge the can into a bowl of cold water, upside down so the opening is below the surface.
4. Bask in the amazement of your friends.
