Abstract
A passive replicator for bubble devices receives a bubble from an input channel and splits that bubble into two bubbles which go into two separate output channels when a rotating magnetic field is applied. The bubble replicator is a single element which has at least three peripheral areas in spaced relation that are associated with different propagation channels. In preferred embodiments, an elongated bar is present in the propagation channels and it is positioned adjacent to and in spaced relation with a peripheral area of the replicator.
