A team of researchers at Technion-Israel Institute of Technology has conducted the first experimental observation of the branched flow of spatially incoherent light—in this case, using liquid dish soap. In their paper published in the journal Physical Review X, the group describes their experiments involving shining light on 2D samples of liquid dish soap and their observations.
