This man-made water fall set up is seen by millions every year. It's right on the main road in Waikiki right next to the beach right along the sidewalk. Sure, it's pretty to look at but it holds a secret to why it's there. Do you know what it is? See for yourself.

On the other side of it is where the public restrooms are.

As it turns out, the people who were staying in the hotels and/or apartments on the other side of the road complained that their view of the beach was blemished by the view of the public bathrooms. I guess enough people squawked about it enough that the city decided to build this tropical structure to hide the bathrooms from their sight.

Pretty interesting.
