What is bioluminescent water that glows at night?

You're walking on a beach at night when the waves start glowing electric blue. You splash your hand in the water and it sparkles like someone dumped a million tiny glow sticks into the ocean. What just happened?
The glow comes from millions of tiny living creatures called dinoflagellates — single-celled plankton so small you'd need a microscope to see one. They float in the water by the billions, invisible during the day, but when something disturbs them at night, they light up.
