exhibit demonstrates the way that attention affects what we do and
do not see. The visitor watches a short video of a group of people
bouncing and passing balls to each other and is asked to count the
bounces. At the end of the video the visitor is then asked how many
times the ball bounced and if they noticed anything "strange"
happen. Upon watching the video again most visitors discover that
they completely missed a very strange and seemingly obvious occurence
due to the distraction of counting the bounces.
