Very interesting and informative. Lots of reading (it IS a museum), kids would be board (but I don't have kids so what do I know). The movie is really cool and takes you back to a time that seems so crazy to us today - for now :/
The gift shop is very affordable, I got a grow-your-own crystal, 3 geodes to crack open, and 2 pouches of freeze dried ice cream for $20!
