Khadija Niazi was asked to set a dish filled with soapy water onto a loudspeaker or other vibrator. When it oscillates, it is possible to hold small droplets on its surface for a long time. She had to describe this behavior and came to the conclusion that various properties help keep these droplets afloat out of which the most important factor is the creation and refreshing of an air cushion between the droplet and water bath. In addition, surface tension differences and hydrophobic parts of the soap help keep the droplet from coalescing. The droplets also exhibit behavior that can be mapped to the behavior of particles at the quantum scale.
