Plastic bottles deserve another chance. They take care of their precious liquid cargo when you have to drink on the go, then most of them get the old heave-ho when empty. This just isn't right, so we're having a Keep the Bottle Contest!

Show us what cool things you can do with a plastic bottle. After you've quenched your thirst, use your head to come up with some cool and funky uses for it. Whether it's super useful, artistic, or just plain silly, we want to see the creative ideas you come up with.

Post an awesome project, and win a Voltaic solar-powered backpack so you'll never run dry on green power! Not only do Voltaics keep you on the go, the fabric in the bags is made from recycled plastic bottles! We'll be giving three Converter bags away: one selected by user votes and two selected by our judges.

Entries accepted from anywhere in the world, and there is no limit to the number of Instructables you can enter! You can only win one prize per contest. Now, get to it and show us your bottles!
