Ping-Pong balls are suspended by 12 air streams via Bernoulli’s principle. The balls interact with each other in a chaotic fashion, each of them affecting the air stream around its neighbors. The behavior of the system can be adjusted by varying the number of balls and the air velocity. At certain settings the balls move gently toward and away from each other in a kind of dance. At other settings the balls jump over each other, seemingly juggled by invisible hands.
