Experiments with water drop splash have progressed to exploring the collision of a water drop and a rebounding water drop. The idea is to delay the 2nd drop until the rebound of the 1st drop reaches its maximum.
My setup - remote flashes to stop the motion of the drop interactions. Flash strength: 1//128 manual mode - with Yongnu remote triggers. A plastic tub for receiving drops and a needle hanging by a tread from the drop maker as a focus. A ring stand that holds the Pluto Valve (drop maker) . In the foreground is a Pluto trigger, camera (Nikon 5300). The Pluto trigger, in water drop mode, provides drop size and drop delay for 3 drops.
A single drop
A rebound drop captured 55 msec after dropping
Collision of the 2nd drop and the rebound drop
Development of the collision
Development of a lamp shade as the 2nd drop collapses. Surface tension appears as a glue that holds the lamp shade as a coherent object.
Continued development of the lamp shade
