Description

Dr Phil Sutton of NIWA explains how the buoyancy of an Argo float is controlled to make it rise or sink. This is based on changing the density of an oil reservoir. He also demonstrates a Cartesian diver, which works on similar scientific principles. This demonstration can be found in the activity Buoyancy in water.
