  1. The boats are an amazing idea! But wouldn’t the old bottles from the water ways be old and have holes in them?

      

    • If it gets in through the gaps then presumably it can also flow out through the gaps? Maybe think of it as a buoyancy aid instead of a boat? Let’s think about this excellent question more?

        

    • Maybe any one in the boat do get a bit wet but the boat as a whole dose not sink all the way, there would still be some water in it.

        

    • Yes, good – some water sloshing around but still floats?
