This is pretty cool video, I've been doing it for awhile now but I really wanted an explanation why it worked and this video shows why.
It's a cool trick to pull off, I normally use the tube of a pen with ends unscrewed. I also have a water version where I direct the water from the faucet with a rubber pipe. It is mad fun but you get water all over the place.

Well try it out haha.

Life is run, it is dance, it is fast, passionate and BAM!, you dance and sing and booze while you can for now is the time and time is mine. Smile and laugh when still can for now is the time and soon you die!

i used to do this all the time with a blow dryer hahaha

i think the ball stays in its place because of the high speed winds that blow past it, same effect you feel when a car runs by you while you're stopped and you feel your car move towards it. the wind blows all around the ball creating a difference in pressure in the center of the blow dryer which keeps the ball in its place.

but i could be wrong ofc

evanthebouncy!, that explanation in the video was actually pretty good. In addition to the koanda effect, the magnus effect applies to the ping pong ball example. The air does not flow symmetrically around the ping pong ball. It 'chooses' a direction and flows around the ball with one general orientation. As a result, the ball does not sit perfectly in the center of the jet of air... it is actually off center.

I'm surprised they didn't fuck this up with attempts to use the bernouli effect to describe this...

Did you know that it is the bernouli effect that causes the universe to accelerate its expansion? Since the stars are moving faster the further away they are, then the pressure must be lower according to the bernouli effect and thus we will have a net force in those directions creating the accelerating effect.

I don't quite understand this. Isn't Bernoulli's principle only valid for fluids? What does the velocity of stars have to do with anything? And isn't the pressure in space close to zero?

It is often used to explain things incorrectly. The Effect in and of itself is fine and valid, but it's easy to confuse how it can be applied to situations.

Seriously. I don't understand this explanation at all. Since when is the universe pressurized?

I think Klockan3 was just sympathizing with my complaints about how people use the Bernoulli Effect. Klockan3, has anyone ever actually fed you that explanation?
