Coffee Cup Challenge




days left



58 billion paper coffee cups are thrown in the trash each year. That's a lot! We think that there are some better ideas for paper coffee cups than just tossing them out so we teamed up with the betacup to bring you the Coffee Cup Challenge! Enter your awesome idea for a paper cup reuse and win a solar-powered Voltaic backpack!

The rules are simple: submit a new Instructable that reuses a paper coffee cup in some way. You can use more than one cup and you can use other stuff along with it, but there has to be at least one cup used.

So get your thinking caps on and start reusing those cups! We can't wait to see what you'll make.

Now that you're warmed up, head over to the betacup where a competition is in the works for the best idea to reduce the number of paper cups that get tossed in the trash. Best idea wins $10,000!
