How to Make a Floating Island

Whether you live in the tropics or near the Great Lakes of Michigan, you can create a floating island as big or as little as you like. Some people have created a livable space on their islands where they can grow vegetation, raise animals and even build small homes. If you want to start off small and try your hand at creating your very own small island, this is the perfect project to get you started. By recycling plastic water bottles and soda bottles, you can create a base for an island that will float on the water.

  1. Take up to 150 empty plastic bottles and place them snuggly into the fishing nets, secure with 12-inch zip cable ties and then set the nets aside.

  2. Take your bamboo rods and place into a waffle or criss-cross position. Secure with the large 12-inch zip cable ties to form your base.

  3. On a secure surface, attach the plywood to the bamboo base using a hammer and nails.

  4. Attach the landscaping plastic by lightly tacking it to the top of the base with nails. Trim the landscaping plastic to fit the base of the floating island.

  5. Flip the base upside down and attach the fishing nets with the bottles to the underside of the platform. Tie a rope with a weighted plastic milk jug full of sand to the handle of the jug and a piece of the bamboo.

  6. Place the floating raft into the water and allow the milk jug to anchor the floating island. Begin to fill the surface of the floating island with 1 inch of sand.

  7. Step carefully onto the island, and plant trees and flowers on the island to create a natural environment.

  8. Use all-natural items such as bamboo or other plants to form a tiki hut or other natural furniture for your floating island.


  • Make sure to bring only lightweight items onto the island; otherwise, it could sink.
  • Have proper lifesaving equipment on the floating island for safety purposes.
  • Do not crush or contort the bottles; they will lose buoyancy.
