@Beals Science, Hi there :) What would happen if; Step1: you had two similar air pumps, you run the 1st and let the ball levitate back and forth to left and right. Step2: You turn on the 2nd air pump also. Does the ball get attracted to the 2nd pump due to pressure change?

[@skizzlemane1]

Garden of AI You would definitely need an air pressure regulator to dial in the flow rate to be as close to the same CFM as one another, and even still I think the air would become turbulent rendering the experiment a failure 🤷🏻‍♂️ just conducting a thought experiment with the knowledge I have (or lack the of lol) of air flow doesn’t seem like this would work at all. IMO but I’d be interested to know 🧐

+Beals Science, Craig, I really do appreciate the work you do to make science exciting. I do the same at several schools and for groups like scouts. ... However... .. I am very sorry, but it is not correct to say that "faster air has a lower pressure." That is the all too common misinterpretation of Bernoulli's Principle. The air out of the straw and blower is at the same atmospheric pressure as all the still air around it. You can easily measure it yourself as shown in the Weltner paper linked below. ... Bernoulli's Principle says that an increase in speed (this is acceleration) of a flow, IS ACCOMPANIED BY a decrease in pressure. .. It says nothing about cause and effect, nor speed past a surface. It is all about pressure differences along a moving stream and the acceleration those pressures cause. .. The science is that a higher pressure upstream in a flow pushes (accelerates) the air to a higher speed because the downstream pressure is lower. There is a net force behind the flow, therefore, speeding the air up. That is why it is faster when it gets to the lower pressure region. This is nothing more than Newton for Fluids. ... It is centered by the Coanda Effect. Air curving around the ball is the cause of a lower pressure at the surface. Think of centrifugal force trying to keep the air away from the curved surface of the ball (actually the air's inertia trying to go straight). This is what creates the lower pressure. When the ball moves to one side, there is air on the other side curving further around the ball. This lowers the pressure more on that side, bring the ball toward this lower pressure. The changing pressures are caused by air/water traveling less or more around the curve causing less or more pressure reduction at the surface, respectively. The same thing happens when you tilt toe flow off vertical. There is air above the ball flowing farther around the curve lowering the pressure more. If you understand this fully, you can even explain why the ball moves further out as you tip the flow more off vertical. ... The lift explanation is also flawed because Bernoulli says nothing about air moving past a surface. The wing is moving past the air and measurement shows us that the air under the wing gets pushed forward by the wing at a faster speed than the air above the wing gets yanked rearward because of the lower pressure above the wing. That upper air actually reverses direction from moving forward ahead of the wing to moving rearward above the wing. This is a high acceleration from the pressure difference from ahead of the wing to above the wing. More change in pressure, higher acceleration of air. ...

@@BealsScience I;m an experienced Electrical engineer. As a volunteer at the Woodstock Illinois Challenger Learning center challengerillinois.org I managed a unique and incredible Boeing 737 full cockpit flight simulator. 5th and 6th grade students got to land the Shuttle at Kennedy with it. An astronaut also flew it. For that task, I decided to refresh my memory on a few things and this is one for which I found a overwhelming amount of poor information on the net, in lesson plans and even PhD books and videos. I talked with some real experts actually in aerodynamics to get a deep understanding. So my quixotic quest is to help getting the poor information straightened out. I'd be happy to get in direct contact if you are willing to go further with any further questions.

[@마틴-r2n]

I got a one question for you. Can you explain for me...what is the difference between Bernoulli's Principle and venturi effect?

[@BealsScience]

I am not well versed on the Venturi Effect, but if my memory is correct, the Venturi Effect is an explanation of the drop in pressure due to a constriction in the area where the fluid is flowing. The Bernoulli Principle deals with the change in pressure due to the speed of the fluid (like Venturi) but is not limited to the constriction of a pipe (or the vessel that the fluid is flowing through).

[@마틴-r2n]

Thank you very much. Have a nice day.

[@Observ45er]

+Beals Science, . The venturi is one of the few places where Bernoulli's Principle applies. .. Pressure is higher in the wide section, but velocity is slower. There's your inverse relationship. ... Think about it. The fluid/air has mass. Newton teaches us that it takes a force to accelerate a mass. Pressure difference is the force that accelerates a fluid. ... In the venturi, the narrow section is a restriction. This causes the pressure up-stream to increase; IN the fat section. This increased pressure in the large section pushes (accelerates) the fluid into the lower pressure, narrow section. Think of the narrow section as a hole in the pressurized fat section; like a hole in a pressurized tank. Regards

I was just glad to finally get it to work! ...now I can move on to a new obsession... Thanks for watching and commenting!

[@bhaktalex]

With all due respect…somethin' ain't right about this so called Bernoulli Principle visualization. You're saying the ball floats as a result of Bernoulli's Principle but here the ball is merely "floating" by the force of the flow below impacting in equilibrium with gravity…and it is staying in place merely because of its shape which causes the flow to be evenly split all around the object keeping it "in place/centered" but this has nothing to do with Bernoulli's Principle. This is simple "holding" an object with a "dynamic" fluid "stick". The flows upward velocity is simply acting as a kind of support column to the object. The oscillation you observe occurs because of imperfections on the ball, imperfect "placement" of the ball into the flow, or imperfections the source of the thrust you are applying…but if you had perfect flow sourse of both, you'd have a perfectly static ball which would not oscillate, supported by a column of air-Having NOTHING to do with Bernoulli's Principle. But I could wrong.

[@tpstrat14]

They’re teaching physics all wrong in school. This isn’t just fun. This is how you learn physics. You can’t just pretend like it’s all in Bernoulli’s head. It’s not something Bernoulli made and put in a book. It’s something he discovered. It’s real. But the way they teach it in school is so egotistical as if it is in fact Bernoulli‘s principle. Books suck

[@BealsScience]

One thing I always try to remind my students is that science is a verb - science is the act of discovering - science is not reading about key words in a book (although sometimes we do have to build a foundation that way in order to be able to DO science). And, I personally think that science education should be fun!! Thanks for watching.

Bernoulli principle is not very important for panes flight. Do not forget you can build a plane with flat wings

[@BealsScience]

Agreed! Attack angle of the wings has a greater impact than Bernoulli

[@thinkingdeep3681]

As it seems you are keeping the ball on the vertical plane. This is not Bernoulli’s principle as per what I have learnt. This is balancing the weight by a force. Bernoulli’s principle applies for the force applied by the pressure gradient. Am I wrong? Please correct me if I am wrong....
