Abstract: This invention relates to an apparatus and method that can provide a group of individuals with an experiential exercise. The apparatus can comprise a source of fluid flow and a channel formation connected to the source of fluid flow at at least two regions of the channel formation. The source of fluid flow can be a vacuum suction provided from, for example, a single vacuum source. The fluid flow can be airflow. The channel formation is adapted to receive at least one projectile therein, and the projectile is displaceable within the channel formation as a result of the fluid flow. The projectile can be, for example, a ball. A gate is located at each region and is movable between an open position and a closed position. When the gate is in the closed position it at least partially obstructs the fluid flow with the channel formation in that region. Further, at least one fluid flow regulator is provided in the channel formation to adjust the fluid flow in the channel formation.
