While washing a thin-layer chromatography plate, Ioan Fuller saw this vibrant blue develop when water hit the plate’s stained silica. Fuller, a PhD student at the University of Otago, had stained the plate with a molybdenum-containing dye so that he could see the various phospholipids in a sample from types of shellfish used in kaimoana, traditional New Zealand seafood. During the experiment, just a few phospholipid spots were blue, but as Fuller washed the plate off so that he could reuse it, the water reacted with the leftover dye on the plate and created this expanse of blue. This design is about 5 cm on a side.
