Abstract
This communication discusses a simple enigmatic attraction at an oil-water interface between like charged particles. The original paper (Nature 420, 299-310, 2002) claims that a distortion of the interface due to a diploar electric field induces a long range capillary attraction. Megens and Aizenberg claims= that this cannot be so due to a fundamental force balance. In this communcation, these authors claim that the range of the capillary distortion is only short ranged and insignifanct (10^-5 kT). The original authors then respond by acknowledging that their original response was not complete but defend their original approach of a capillary distortion. This is true when but only when the free charge density of the oil is accounted for, thus a large dipole imbalance can be created.
