Survival whistle from spent cartridge

Have you ever needed a signalling whistle, but just so happened to leave yours at home? All you need is a spent big-game-sized cartridge and a lung or two full of air to make a loud whistling sound that can be heard for hunrdeds of yards. Simply blow over the opening, and with the right amount of air, angle, and practice, you should be able to make a high pitched signalling whistle for the next time you need to communicate with your buddies!
