Amazing Fluid Dynamics Experiments - From Electric Currents to Magnetic Swimmers

Explore a captivating 12-minute video showcasing a series of fascinating fluid dynamics experiments presented by Professor Tom Mullin from the University of Oxford. Delve into a wide range of fluid mechanics phenomena, including turbulence, wave formation, Rayleigh-Taylor instability, viscous effects, magnetism, electricity, segregation, disorder, and chaos. Witness experiments such as electric current in liquid crystals, segregation of metal balls and poppy seeds, granular material behavior, waves in rotating drums, viscous fluid instabilities, floating objects, and magnetic swimmers. Gain insights from this comprehensive demonstration of fluid dynamics principles, supported by the Journal of Fluid Mechanics (JFM) and the UK Fluids Network (UKFN), and produced by Dr. Tom Crawford, an Early-Career Teaching and Outreach Fellow at St Edmund Hall, University of Oxford.
