if you set a dish filled with soapy water onto a loudspeaker or other vibrator and make vibration, When it oscillates, it is possible to hold small droplets on its surface for a long time. I mean, when the liquid surface starts vibrating, some drops of the same liquid, Spontaneously appear on the surface of the liquid.
What causes this phenomena? Why do the drops appear?
This is different from another question . the defference :
In this question some drops will be *created Spontaneously * But in the other question drops wich are put on the vibrating surface won't coalesce.
