Posted June 3rd: Rayleigh-Taylor in the bathroom
An absolutely brilliant example of the Rayleigh-Taylor instability of two fluids occurring by accident in the home. This instability occurs when a denser fluid is placed on top of a lighter fluid in a gravitational field. (It can also occur under other circumstances) The heavier fluid begins to sink into the lighter fluid below and often forms the characteristic mushroom-like shapes seen here.
The redditor who posted this stated “Soap dispenser was half empty, filled it with a different soap. Looked like this the next day”
What’s interesting here is that in this case the densities of the liquids were such that the movement of the liquids was very slow as compared for example to this.
