If you carry a small survival kit, you should consider adding a condom or two. Many know that they can carry water, but they also work well to help start fires, keep items dry, and can be made into a slingshot.
Wilderness skills weblog Willow Haven Outdoor shares a an article and a series of YouTube videos on the many uses of condoms in a survival situation. Non-lubricated condoms excel at holding water but they're very delicate. They are also handy to use as a firestarter — once lit they'll burn for a few minutes, and can be used as part of a bow drill to make a fire. They can also keep items such as tinder dry during a rainstorm.
