The second most relaxing thing to do on the planet, after visiting a spa, of course, is visiting an aquarium. The silence and the shifting colors of an aquarium are hypnotic. I’ve never snorkeled or did any kind of water activity or sport other than water ballet, so the aquarium is my key to a world that’s very mysterious to me. So here–enjoy some soothing eye candy and think peaceful thoughts. And remember to take care of oceans, lakes, and rivers. Go chuck your garbage in a trash bin, not on Mother Earth.
