If you forget your wallet, an old chapstick attached to your keychain can bail you out. TheBestHobbiesBlog turns that old tube into an emergency money stash.
All you'll need is a pocket knife, a hot glue gun and a key fob. The video details how to open up and remove the insides of the chapstick, and attach the fob to it with some hot glue. The way he folds up the money is also interesting, as it comes out attached to the cap.
Those who have a spare chapstick but no need for a spare wallet could look at turning it into tangle-free storage for headphones instead.
