Hovering Ball

The Hovering ball as the name suggests hovers or levitates above the ground. It works on the principle of air pressure. It creates an air pressure that lifts the hovering ball above the ground. There is very little frictional force between the ball and the ground, which lets the ball slide till a far distance.

How does it work?
The hovering ball is a wonderful example of Bernoulli’s principle. The same principle allows for heavier-than-air objects. The power of air allows you to levitate a ball in mid-air. The air from the blower, as you blow through it, produces the levitating ball phenomenon. The fast air moving that you are blowing around the sides of the ping-pong ball is at a lower pressure than the surrounding stationary air. If you look closely, you’ll see that the ball wobbles while it is levitating in mid-air. The ball is attempting to leave the area of low pressure, but the higher air pressure surrounding it forces it back into the low-pressure area.
