Physics
Capillarity and surface tension
Explore capillary rise and depression by changing tube radius, contact angle and surface tension. Compare the viscous approach to equilibrium with Jurin height and capillary pressure.
Try this
Compare three radii in one bath. Change wetting to turn rise into depression.
