Earlier this month I posted about the clever Bote toy boat made of cork and white plastic. Today I have an even more simple idea that could make a great DIY project. Dutch design team Floris Hovers has this simple concept to turn any shampoo bottle into a bath time boat. I'm sure with a little handiwork, a sewing machine, and some rubber bands, you could whip up the same thing.
If you are fluent in Dutch, read about the Flessenboot here.
Otherwise, just make one and send us a picture.
