Thoroddsen et al. supplementary movie
Movie 1. A high-speed video clip taken at 20,000 fps, showing the impact of a drop onto a thin film of ethanol coating a glass plate. A fine spray of ethanol droplets is thrown up by the impact and is subsequently brought down by the airflow around the edge of the crown. As these droplets touch the crown they produce gradients in surface tension, with the ensuing Marangoni instability puncturing numerous holes in the crown. The drop is 89% glycerin/water mixture and its horizontal diameter is 5.0 mm. The ethanol film is about 35 micrometres thick. The impact Re = 460 and We = 5720, based on the liquid properties of the drop. The times are in microseconds.
