My kids and I recently visited the Museum of World Treasures in Wichita. It was an extremely positive experience and I highly recommend it. We were thrilled with the wide variety of items on display, but especially impressed by the fact that you could really get up close and examine so many of the items on display.
I can probably say more with pictures than in words: An Egyptian Mummy A big cat of some sort. Rubbing the Buddah's Belly
If you are in Wichita, don't miss this museum. It's worth a road trip if you are looking for something to do.
