If your out camping or out on a picnic and completely forgot your corkscrew for your wineglass then you can easily still remove the corkscrew from your bottle to enjoy your wine. To do so you will need a towel and to find a tree. Wrap the bottle in a towel and walk over to the tree. Beat the bottom of the bottle against the tree for a good couple of minutes. The beating of the bottle should loosen the corkscrew from the top of the bottle. Next after your finished grab and corkscrew with your hands and pull it out of the bottle. If you still can't pull the corkscrew out then beat the end of the bottle again until you can.
