Streamlines is a miniature wind tunnel which museum visitors can use to visualize airflow patterns around a variety of objects. Brightly lit streamlines of air and water vapor flow from one end of a chamber to the other. Visitors open the clear chamber lid and place objects into the airflow. The mist swirls around the wing cross sections, cubes, spheres, and cityscapes revealing laminar and turbulent airflow patterns. Visitors can vary the airspeed of the streamlines to create different effects.
