In the video made by the slo-mo guys as shown here, at time 1:47 comes a moment when a water droplet(almost completely spherical), is seen to 'float' on the surface of the water for a while.

So why did this case arise? Is it something to do with the tuning fork, or solely a surface-tension based phenomenon? If it is the latter, why does it break back into the whole liquid,and is there an ambient temperature and pressure for this to occur?
