A nice flat collision shot from red food colouring dropped into good old fashioned tap water.
Another one from my black and blue session, the very early stages of drop drops colliding mid air. Black food colouring with a blue gelled flash.
I nice mid air collision from a drop moving upwards from the top of the spike and one coming down. Black food colouring with a blue gelled flash.
This one reminds me of a cocktail glass, with a cherry. It is red food colouring dropped into plain water.
