Need an emergency tripod for a small compact camera? All you need is a drill, 2-inch ¼-20 bolt, an empty bottle and a cork. Drill a 14-inch hole vertically through the cork's center, insert the bolt and voilà, a tripod head. Now refill the bottle with water or sand, and there's your camera support.
