Aluminum cans are convenient! So why would we need a better soda can? Well because even though they're recyclable, they're not really reusable. This soda can is not only reusable, it's also biodegradable. Better for everybody!

It's humorously called the TIN CAN though its made from PLA (poly-lactic acid), which means some sort of corn starch that can retain some plastic properties (and also, one of the better eco-friendly materials around). Basically, it's a nature-friendly thermos with a unique design. I'll take two. $28 [Hao Shi via Yanko Design]
