Superwalkers

Walking droplets – drops that bounce their way across a pool of the same liquid without coalescing – have fascinated researchers in recent years with their unusual behaviors, some of which mimic quantum phenomena. In a new experiment, researchers vibrate the pool at two frequencies simultaneously, which helps support much larger droplets, known as superwalkers. When the two driving frequencies are close to a harmonic match – like at 80 Hz and just under half that at 39.5 Hz – the droplets will walk, then come to a stop, and then begin walking again.
