This fountain is located at the Christian Science Center, right in front of the reflecting pool.  The fountain is open to young and old who are looking to cool off on hot summer days/nights. Unfortunately, when I took this photo there was no one playing in the fountain. I think it would be fun to have a shot of some kids running through the streams of water. 

I just read that when the sun goes down the water becomes illuminated with light. I guess I'm going to have to go back at night and get another shot.
