Ball suspended in air at a slope

This is in response to Ben Krasnow's video about floating screwdrivers.

My intuition was a smaller object would not be stable in an angled airstream due to the horizontal component. Clearly I was wrong, the item remains trapped in the stream even if it is off vertical quite a bit.

You see a solid 32mm plastic ball with one threaded hole floating in compressed air at an angle of about 60 degree. The noise increasing in frequency is due to the spinning of the ball and the air hitting the tapped hole.
