Red tide spawns blue light show at night on San Diego coastline: Algae blooming since late August have turned the waters brownish red in the daytime. At night, waves trigger flashes of blue light. Bioluminescence occurs when the algae cells are jostled in the waves. The light show has been dazzling visitors this week, but experts don’t know how long it’ll last.
Aaaand, more fun with science:
One family at Tamarack Beach in Carlsbad was collecting the seawater in bottles to generate a similar effect described in the North County Times. “If you dump the bottles in the toilet and turn off the lights, it will light up the whole bowl,” Duane Collings of Oceanside told the newspaper. “It’s a trip.”

Aw man, I remember this happening in high school—summer of ‘05? It was totally mesmerizingly awesome.
