Very cool and interesting museum. Give yourself at least 2 hours to see and read all the exhibits. Learn about the Atomic Testing done years ago in Nevada, about the people working in the community called The Mercury Project--they were a bunch of scientist and engineers dedicated to the atomic testing projects and lived in bunkers, etc so interesting! Also see what the atomic bomb looks like as well as learn about the then very top secret Manhattan project--now a TV series! Oh and don't miss the Area 51 Exhibit! Alien / UFO madness! So fun!
