This was a lot of fun to learn about the history of the atomic industry in Vegas. It was an informative experience, but also information overload to go through and read all the exhibits. My favorite part was the area 51 Martian exhibit. It was so cheesy, it became so awesome! If you want to go for the truly academic experience, keep an eye out for the lectures that they host and check out the reading room. They also provide a free children's activity book - you can also download this online. I also bought some rocks (geodes) at the gift shop that you can break open later.
