TF1.1 Air vacuum
This consists of air from the high pressure nozzle on the table rushing out of the center of a disk. Another disk fits closely over the top. Because of the way the air will flow, the top disk will be sucked down. Strings are attached to the top disk so that a volunteer can try and pull the top off. The same applies for the apparatus in F56. A funnel is attached to an air hose and a ping pong ball will get stuck in the funnel. Another example is to reverse a vacuum cleaner so that it blows air (2102 prep room). Thereby, a ping pong ball can be suspended in air. Bending it on an angle will cause the ball to spin, but still stay suspended.
