The motion of fluid induced by precession plays a crucial role in a wide range of phenomena and applications, including spacecraft rotation, atmospheric vortices, and the flow dynamics within Earth’s liquid outer core. It has also been implicated in the generation of dynamos observed in celestial bodies such as the ancient moon and the asteroid Vesta. The experimental aspect of precessional forcing is particularly fascinating because it offers a natural and efficient method of driving conducting fluid flows on a laboratory scale without needing a propeller or pump.
