This exhibit has two separate stations, each of which holds four touch-sensitive objects. When visitors are not touching the objects, the exhibit lights the objects in a simple sequence inviting visitors to follow the pattern by touching the objects in sequence. If visitors follow the sequence, the exhibit blinks a slightly longer sequence. The sequences continue to get longer and more difficult for as long as visitors continue to get it right. This exhibit is popular with families and groups of friends because they can cooperate in following the patterns.
