Each year, the “Gallery of Fluid Motion” highlights the videos submitted to the Annual Meeting of the APS Division of Fluid Dynamics.
And each year there are some brilliant videos featuring physics that you could (with a bit of experimentation) see in a coffee cup.
This is one of this years winners - and while the authors don’t mention this explicitly - it’s what could happen if you put your #coffee cup on a #loudspeaker
