Endless fun playing with a #rheoscopic fluid. Used a bit of red food coloring this time.

The obstacle is a pencil, stationary, while the lazy Susan spins underneath with the fluid. The #rheoscopic fluid (easily made at home, more on that on another post) allows the currents to be seen easily. An instability makes the fluid "oscillate" and create the von Kármán vortices as it flows around the pencil. Here's a video:

This is a rotating shallow water #experiment, essentially a lazy Susan powered by a #LEGO motor and filled with a #rheoscopic fluid. Here's the setup:

This fluid, seemingly at rest initially, turns out to be convecting as revealed by a #timelapse movie. #Evaporation cools the fluid at the surface, which makes it a bit heavier than the fluid below, thus #convection ensues, very slowly!
This fluid is #rheoscopic, easy to make at home using shaving cream.
Here's the recipe:
