I am going to try an experiment with them I saw on a documentary one. Tie the bottles together by the handles or put them in a large net and use it as a floating island on our dam as the ducks and geese when I get then can use it for a retreat for getting away from preditors e.g. Foxes.
I saw a fellow in Mexico do thid and he actually lives on his bottle island.
Gosh here I am rambling on. i will post the results when it is completed
