What caused the ball to float on such a jet?

A ball with styrofoam foam (often used for insulation) can float in the air thanks to the push of a jet of water, this is absolutely true, not a magic trick. Let's find out what miracles happened.

1. Decoding the magic tricks "matchstick knows dancing" is surprisingly simple

Perhaps many people have tried to take the ping pong ball and put it on the hair dryer, when the ball is turned on, the balloon will float overhead. According to Bernoulli's principle, when the ball falls off the edge of the airflow, it causes the airflow to slow down. This causes the thrust to increase, causing the ball to move back to the center, creating an equilibrium to help the ball float in the middle.

But with a jet of water, it is different, according to the author, YouTuber Veritasium, the force of vertical water always drives the ball out of the flow, and also makes it spin. When the ball rotates, it creates a jet of water that comes out from the side that does not come into contact with the flow. This created a reaction that pushed the ball up and caused it to return to the water. It is these forces that create an equilibrium, they automatically adjust to each other so that the ball is always floating above the flow.
