The floating ball demonstrates 18th century mathematician, Bernoulli’s principle, in regards to air pressure. This same principle is used in air craft designs to keep planes in the air by creating lift. As long as air keeps blowing from the tube, the ball will continue to levitate. Other activities include the magic floating saucer, bubble blower and magic control.
