I saw some pictures that my sister took when she went to the World. One picture looked really neat, but I don't know where it was....It was a large flat surface, that you could walk on, but it had holes in it that would shoot water up. I think it went to music, but you never knew where the water was going to come up. Does anyone know what I'm talking about, and where it is located? (hopefully, I'm not imagining things!)
