Acoustic eruption —

This video shows the transfer of mechanical energy and radiative pressure from Surface Acoustic Wave (SAW) travelling onto a solid surface into a droplet of water, dropped in the propagation path of SAWs, at 100k fps acquisition (slowed down 500 and 1500 times). The behaviour resembles an eruption and is used in medicine nebulisers.
