POPSLevitation in the Lab continues: Several years ago, acoustic levitation was introduced to keep a droplet separate from its surroundings but the equipment required for this is complex, big and expensive. Alternatively, the technique of bouncing droplets was introduced in 2005 but until now it could only be used on a specific range of droplets with high viscosity. The new technique which the physicists began work on three years ago, when one of the researchers noticed that certain bass notes emanating from his iPod speaker could make droplets 'roll' and appear to dance, works for a much larger range of viscosity fluids than previous techniques and also for a larger range of droplet size – making it much more useful for chemists, biologists and food scientists.
