For the enterprising minds among us, plastic water bottles are capable of being used to help create an island. Richart Sowa has done this (twice) in Mexico, using over 150 thousand bottles as the foundation for his Joyxee Island. Plastic bottles float, so if you collect, or rescue, enough you can create your own floating island, or settle for a raft. One way of lashing the bottles together is to cover them with netting. Remember, the only limit to what you can do with a plastic bottle is your imagination.. or your internet connection.
