A fun little thing we'd always like to do in Maine is sit on the wharf at night and kick up the bioluminescence. Pretty though it is, it always sort of freaked me out for some reason (to know that bacteria are creating it and that the sea is so chock-full of life and light?).
The Milky Sea phenomenon is apparently created by a different creature from the ones we like to play with summers. I'm having a hard time wrapping my mind around a patch of glowing ocean so massive that you can see it via satellite.
