The team exploited an effect called non-photochemical laser-induced nucleation (NPLIN), which was discovered by serendipity a decade ago2. Scientists led by Bruce Garetz at the Polytechnic Institute of New York University in Brooklyn found that shining pulses of laser light into a solution of urea in water triggered crystal formation>Cool! I want one for Christmas!
Hey, you haven’t been to one of my family Christmases.
