In a store-window vacuum cleaner display, a table-tennis ball is suspended in midair in a jet of air blown from the outlet hose of a tank-type vacuum cleaner. The ball bounces around a little but always moves back toward the center of the jet, even if the jet is tilted from the vertical. How does this behavior illustrate Bernoulli’s equation?

Question

In a store-window vacuum cleaner display, a table-tennis ball
is suspended in midair in a jet of air blown from the outlet hose of a
tank-type vacuum cleaner. The ball bounces around a little but always
moves back toward the center of the jet, even if the jet is tilted from the
vertical. How does this behavior illustrate Bernoulli’s equation?
