Experiments were performed to measure the size of drops resulting from the capillary breakup of laminar liquid jets. Random noise was used to perturb the jet and an electro-optical instrument was used to measure drop sizes. Drop size distributions show two peaks as predicted by nonlinear theory. The large group has a mean size as predicted by the most unstable perturbation mode, in agreement with the commonly accepted but previously untested assumption.
