A combination of forces from the ultrasound waves, the spinning droplet, and the fluid moving within the droplet drives particles inside the droplet to move in a helical pattern, essentially corkscrewing through the droplet to come together at a central point.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Researchers have detailed the physics behind a phenomenon that allows them to create spin in liquid droplets using ultrasound waves, which concentrates solid particles suspended in the liquid.
