Construction of a Simple Construction of a Simple DiverDiver
Fill a bottle with waterFill a bottle with water Put a partially filled test tube upside Put a partially filled test tube upside
down in the bottledown in the bottle Make sure it floats just above the Make sure it floats just above the
waterwater Seal the bottle and apply pressure Seal the bottle and apply pressure
More water goes into the diver so it is More water goes into the diver so it is more dense and goes downmore dense and goes down
Now you have a Cartesian diverNow you have a Cartesian diver

How Does a Cartesian How Does a Cartesian Diver Work? Diver Work?
Diver floats because it is less dense Diver floats because it is less dense than waterthan water
Pressure is applied Pressure is applied Diver becomes more dense than Diver becomes more dense than
waterwater Diver floats to top when pressure is Diver floats to top when pressure is
releasedreleased
That’s a Cartesian Diver!That’s a Cartesian Diver!
