Found a washing up liquid bubble still around from last night! I wonder what's causing the motion: just slight air perturbations, Marangoni flow due to varying surfactant concentrations? What do you think?
Interesting shooting droplets across the surface of the coffee this morning. Might not have anything on @Dunc76's berry buoyancy but damn isn't fluid dynamics cool!
This is an amazing video. A remarkable example of vortex reconnection and conversion between twist and writhe as the vortices kink. Important for understanding both fluids and the evolution of magnetic fields! @FluidsLeeds
