Caption: Physics professor Cary Forest with a one meter stainless steel sphere fitted with two motor-driven, opposing propellers. The equipment is part of a water-based prototype design being used by Forest in his geodynamo experiment to simulate the natural, magnetic field-generating dynamos inside the Earth's core.
