Unfortunately, it will probably be a while before we can get rid of plastic bottles for good, so designs like the Bottle Cap Sharpener are even more important. It gives new life and purpose to used plastic bottles that are just lying around or sitting in the trash.
Designed by Yuchen Liu, the Bottle Cap Sharpener essentially comes with a built-in pencil sharpener. Once your drink is finished, instead of throwing it out, you rinse and wash it so that you can use it again. When you sharpen your pencils, the bottle conveniently collects all the shavings so that you don't have to worry about the cleanup.
Simple and clever, the Bottle Cap Sharpener offers a great way to reuse a plastic bottle.
