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
