Last summer our kids took us to go through the glass labyrinth located in the front yard area of the Nelson-Atkins Museum of Art in Kansas City.
A labyrinth, as you probably know, is a maze, an irregular set of passageways that make it hard to find your way through from the beginning to the end. The walls of the passageways can be made out of all kinds of materials- hedge bushes, corn stalks, hay bales, mirrors or in this case, glass, making the walls see through.
It was fun to stand and watch for awhile. The adults had their guard up, but kids went in quickly and would run pell-mell into the glass walls. They would stop, confused, feel with their hands, turn, and then move forward quickly again till they hit another wall, and then another.
