  3. Why Cartesian Divers? • Subject of density found interesting • Evolved from previous idea • Needed an exhibit for the water room • Subject was well known by group Stow Girls Get SET Team Summer 2002

  4. Construction of a Simple Diver • Fill a bottle with water • Put a partially filled test tube upside down in the bottle • Make sure it floats just above the water • Seal the bottle and apply pressure • More water goes into the diver so it is more dense and goes down • Now you have a Cartesian diver Stow Girls Get SET Team Summer 2002

  5. How Does a Cartesian Diver Work? • Diver floats because it is less dense than water • Pressure is applied • Diver becomes more dense than water • Diver floats to top when pressure is released That’s a Cartesian Diver! Stow Girls Get SET Team Summer 2002
