Full Answer

  1. Make holes on one side of the bottle

    Use a screw driver or nail to make three holes, in a straight line, on one side of the bottle. Ensure that the holes are big enough to let water in and out of the bottle.

  2. Tape coins to the bottle

    Tape five heavy coins on either end of the bottle, on the same side as the holes. The purpose of the coins is to weigh down the submarine.

  3. Attach a flexible straw

    Attach a flexible straw at the mouth of the bottle. Use modeling clay to secure the straw in place, making sure that the area is water tight. The holes and the tip of the straw should face opposite sides of the bottle.

  4. Add plastic tubing

    Add a length of plastic tubing at the end of the flexible straw. The length of the tubing will be determined by the depth you want to achieve.

  5. Operate the submarine

    Ease the submarine, holes side down, into a water tank, and allow it to sink. Blow into the plastic tubing to let water out of the bottle, and float the submarine.
