Watch These Water Drops Levitate And Form Spinning, Pulsating Stars



The drops, held in a node of low pressure and supported in mid-air by a high-pressure zone sat beneath them, can be excited by different frequencies of ultrasound. When the frequency matches a multiple of their resonant frequency, they show weird modes of oscillation, forming stars with three, four, five or however many points — the number matching the multiple of frequency. But all that science aside, don’t they look pretty? [New Scientist]
