Capturing a photographic image of the exact millisecond that two waterdrops, that are travelling towards each other (one from above & one from below) at a speed that the human eye cannot record actually collide.
The image ‘Almost There’ will give you an idea of what I mean.
We can see here the ‘Spout’ or ‘Jet’ projecting upwards to meet the next ‘drop’ of liquid before the actual collision.
The ‘Spout’ or ‘Worthington Jet’ is named after the physicist who discovered it in 1908.
THE PIONEERS.
Arthur Mason Worthington (11 June 1852 – 5 December 1916) was an English physicist and educator.
He is best known for his work on Fluid Mechanics, especially the physics of splashes, and from observing those, he pioneered techniques of Highspeed Photography.
Worthington’s pioneering work would later be overshadowed by the work of Harold Edgerton in the 1930’s. Improving on Worthington’s techniques, Edgerton’s highspeed photography using a stroboscope could produce up to 3000 images.
