Keep a close eye on your kiddos or they will disappear in maze of tunnels and fly off the side of the museum in an old plane. This is definitely a museum that will give the whole family a workout as you explore the sprawling jungle of exhibits crafted out of pieces salvaged from history. Some items are beautiful in their own right, while others puzzling sculptures have been pieced together by museum artisans. Dreamed up by renowned artist Bob Cassilly, the museum opened in 1997. If you’re ever in St. Louis, the museum is definitely a must see.
