It seems like the bottles get all the attention when it comes to recycling. If more people saw these bottle cap creations I think they would think twice before giving up their hard earned bottle caps for recycling.
Implications - For example, can you believe there are people out there that have created life-like portraits of presidents entirely out of old bottle caps? That's crazy. Or how about the cutesy eco-jewelry that uses old tea cans to craft Hello Kitty necklaces. There's pretty much nothing you can't craft out of old bottle caps.
