I am all for waste reduction and recycling, but I am not sure about the Rethink, a clothes hanger that needs two plastic bottles to be complete. The Rethink starts off as a hook with two holes that are threaded to accept standard sized soda bottles. Functionally it makes sense and will provide a nice rounded support for shirts. Forget about hanging pants and you better have a big closet because your hanger just got quite a bit wider.
At $8 each, the Rethink isn't cheap, but at least you can keep several bottles out of the landfill.
