Water bottle submarine? Answered

Is it possible to make a submarine out of water bottles by allowing them to fill up with water to increase weight and make you sink? I am going to the beach soon and want to know.

I recommend starting with one soda bottle, and trying to build your own "Cartesian Diver."


Submarines, big and small, have a large air bubble, as part of their volume.

Changing the size of the air bubble, by somehow, moving water in or out of the same space, changes the total volume of the submarine, and thus changes its bouyancy.

If you can learn how this principle works, you will be better prepared for building a submarine.
