Direct Measurement of Lateral Capillary
Forces

Microscopic photograph of two capillaries protruding through an air/water
interface and interacting via their menisci. We constructed a precise electronic
microbalance and were the first to report experimental data of
the strenght of the interactions on an absolute quantitative scale. The
data are in very good correspondence to the theoretical predictions and
demostrate interesting non-linear effects in the cases were no theory is
available yet.
