💧 Surface Tension Lab: Capillary Rise, Exact Meniscus and the Largest Pendant Drop from the Young-Laplace Equation

Dip glass tubes into water, ethanol, glycerol or mercury and watch the Washburn rise settle at Jurin's height, then hang a drop from a needle and find the largest drop it can hold by integrating the Young-Laplace equation, with the capillary length setting the scale.
