E and R at the interactive exhibits at McDonald Observatory. This particular exhibit teaches about the nature of light. It's a great room to spend a spare hour or two before a star party. The exhibits are interactive and explain science topics at the level accessible to children, but without oversimplification. There is also some stuff to climb on for younger kids, and a long, curved bench for parents to sit on. I even got some work done on my laptop there, except that the McDonald Observatory visitor center does not have public WiFi, and no cell phone signal, so you can only do what you can do without an internet connection.
