Prepare to be blown away by this 40-foot tornado—a vortex of swirling, illuminated vapor rising continuously from the floor. Manipulate and measure the dynamics of this vortex from both levels of the exhibit. Surrounding the base of the vortex are control panels for shaping the air column with a series of dampers. Viewing from the Balcony Level, you can activate lasers to cut through the vortex and reveal its laminar (smooth) and turbulent airflow patterns.
