there was a children's part of the museum that was an exploration center where the kids designed bridges and buildings and tested them under earthquake and windy conditions. here is a picture of us taking over the kids play room and building an arch. it took us about 5 tries to get it to work. the comotion made all the little danish kids interested so they built an arch too- but it only took them one try. the danish instructors who were are age couldnt stop laughing at us "crazy" americans.
