Dad's Notes:  Hands on science exhibits, theater of stars, laser light shows, minerals & gem museum, nighttime observatory and, of course, a gift shop. Motion machine, bell jar, vortex and more hands on exhibits. Shows start promptly - no late seating, no kids under 3 allowed.
     You can go just to the Mineral Museum (which would include the numerous science exhibits) without going to the laser show - If laser shows aren’t you thing I still highly recommend this place just for the science exhibits and mineral museum.
     The Observatory is open in Evenings Wed - Sat Just after Sunset till 10 PM. The gift shop (Called the Science Store) is full of great science toys and experiments!
