For at least a decade, Jack Long has paired his day job in advertising photography with a growing archive of personal projects that explore the energetic, dynamic qualities of liquid. His latest series centers on circular pools of water that splash outward, creating colorfully tiered layers that build up the dimension of a typically gravity-bound material. Although the liquid appears to be spraying outward after being punctured by an object dropped from above, it is actually gurgling upward from a custom-designed fountain. Long shares with Colossal that the machine took about two years to build and produces pools that reach about 30 inches in diameter, which he has to photograph within a fraction of a second to capture the perfectly concentric effect.
