Amazing Effect When You Put a Whirlpool in a Vacuum Chamber


The Action Lab
The Action Lab

As some have pointed out there is definitely more going on here than just air pressure. In fact you cannot talk about any fluid flow with only talking about pressure. You have to always talk about fluid velocity and pressure together. We do know there is the centrifugal effect of water being thrown out the sides and also down the middle. But the reason there is ever any flow at all is due to pressure differences. The ball is being dragged down by the water but it is also moving fast and so the atmosphere pushes it down as well. There is also rarified air and eater vapor that forms under the ball pushing it up (maybe). This is definitely a phenomenon that I have never seen before in any literature so if anyone has any resources are open to hear more about this.

Do the same test but with the whole bowl in rotation instead of using a rotor at the bottom. I bet you'll see the paraboloid water but the ball won't sink. The reason the ball sank is because the rotation is created at the bottom and the rotor acts like a pump sucking water in the middle and throwing it to the sides. This creates a water stream going from middle of the bottom to the sides then up along the sides then to the middle then down in the middle. You could add some glittery stuff into the water and you'll see that the water as a combination of 2 movements: rotation and the described convection like one.

The Action Lab this might be a crazy question, here goes. When you put water in your vac chamber, do you remove gases from the water? Does this decrease the volume while the atmosphere is reduced? If so would the gases stabilize once the atmosphere is restored?

I see there left little air under ball. Maybe that air expands and pushes ball upwards and that air trapped and couldn't escape. Maybe you first lower the chamber pressure first to get rid of air inside water then create whirlpool.

So following this logic, a churned sea, as in a storm, would make the vessels in it less buoyant. If that were true, then heavy laden ships would be in great danger in a sea that is troubled. This trouble would stem from the changing property of water and would present a danger to the ship for another reason besides waves. It seems to me that some consideration has to be given to the atmospheric pressure that exists inside the ping-pong ball. If the ball is sealed, then it will try to expand as the pressure decreases. Could the ball be acting like the air bubbles that are rising in the water as the pressure decreases on the water? The ball is full of air, perhaps it wants to rise for the same reason as the air bubbles rise. Perhaps the air bubbles break the surface tension on the ball and act like a lubricant causing the water to loose its hold on the ball. I would like to see the effect, if any, of the same vacuum on the ping pong ball alone, and also on the water alone, churned and calm. I am not sure of the properties of water in a vacuum. There are too many other contingencies to consider to be able to draw an immediate conclusion.

Most of your premises are definitely flawed. Like how how does the atmosphere that push down to create the actual hole in the vortex when the pressure is distributed evenly? You're probably on the right track but the video is just misleading when we don't get the most important parts of what's actually going on.

By blowing on the straw and it sprays a mist out... that's basically how carburetors work. They are always supplying fuel no matter what. This is why its best to get as much swirling action from an intake when dealing with carbs. You want the air to mix the best it can with the fuel. Fuel injected engines swirl the air but mostly in cylinder. However, the fact that its a non-stop fueling with carbs is why they are less efficient than fuel injected which sprays just the right amount when needed.

Great experiment! Overall air pressure has no direct effect on the ball - it pushes it down (via water) as much as it pushes it up. But the lower pressure allows building of steam- bubbles. They gather in the middle where the pressure is low and they build eventually a vapor column that wants to go up and pushes up the ball. It would be interesting to see the experiment with slightly warmer or colder water...

I think you missed something really early on which made your question pointless: it can't be the air since the ball is *completely* enveloped in water. The best you can do is say the depression in the vortex is because of the air, but it's still a whirlpool

This is the second video I have seen of yours which I feel that your explanation of what is happening is inaccurate or at least poorly informed or explained. Take the straw demonstration, it is 'good' in that it clearly shows that the air pressure drop across the top of the straw is sufficient to cause the water to climb up the straw and be blown out. However, that had next to no bearing on what the ping-pong ball experiment showed and you tossed 'air pressure' around as if it explained something, perhaps you can try drawing the forces on a chalkboard or something, either during the video or beforehand to iron out the script. Just trying to give some feedback to help future videos.

That's NOT air under the ball. What you see is water cavitation (water vapor) . That's something commonly occurring when you rotate a propeller at high speed under water. Normally it can't happen at the low speed you have in your vortex generator but since you also lower the pressure by sucking the air then cavitation occurs at lower speed.

If Air pressure would have to do anything with this the vortex would get smaller not bigger in vacuum. Not pressure, no pushing down anything, like the "air" in the vortex-channel. Maybe i am total wrong, but i would beet, that if you spin faster with less water, so that the vortex touches the ground by its own, the ball would come up also.

My theory is, the mixer on the bottom part pushes the water sideways then hits the glass then detours upward. As it goes up the biddle area of the water has lower pressure so the water that went up the sides are being forced down towards the middle that force is what keeps the ball submerged. The only reason why it floated in the vacuum chsmber is because there's air pockets below it. Why you overthink too much?

I think the ping pong ball was sucked down into the center of the vortex because the vortex is basically acting like a centrifuge and the ping pong ball is less dense than the water so it is pulled into the center. The downward current of the water in the center then brings the ball to the bottom. If it was the atmosphere causing the ball the sink, the ball would only sink until it's top was just below the water's surface, after which, the atmosphere couldn't push on the ball anymore without moving more water out of the way first. The reason the ball lifted up from the bottom when vacuum was applied, was because that where dissolved in the water (and possibly some water vapor itself) came out of solution. When these gases precipitated out of solution they became much less dense than the surrounding (still liquid) water and were pulled to the center of the vortex. In the center of the vortex where the centripetal influence of the vortex is negligible, the gas tried to rise up to the surface. But for the gases under the ball, the ball was in the way. Normally the gas would go around the ball but in this case they couldn't without being overpowered by the centripetal forces at the ball's edges that push them back to the center of the vortex underneath the ball.

I honestly feel like you're missing a test - lowering the pressure before starting the vortex. Currently you might simply be causing the water vapour caused by the lower pressure to be stuck under the ball.

Good job, dude! You're on your way to understand how gravity really works. This is "centrifugal gravity" =) The water doesn't "suck the ball down". The ball actually falls into low pressure zone. Now think the same thing but to centripetal process... Then you'll understand how planets "attract" each other. And how parallel conductors "attract" each other. When actually they are just being pushed towards one another. All this is just an Energy conservation law explained with Bernouli's equasion.

I disagree with your conclusion completely. The ball is rising up during your vacuum experiment because your "impeller" is now inefficient due to cavitation. The water is simply being forced to the edge of the container through centrifugal force, as a result making the water pressure lesser at the centre of the container, in turn making it unable to hold the weight of the ball. When the vacuum is achieved the *water vapor* (not "dissolved air") is interfering with the forces needed to achieve the required centrifugal force. You could also use a larger hose if you want the vacuum pump to work exponentially faster for your experiments.

Does the weight of the system increase when the ball is submerged? It would make sense, because replacing water with external forces usually increases weight.

Your guess is pretty ok but you forget something; the ball floats, mostly because its pressure inside is way bigger than the pressure of the water due to the vaccum action, try that experiment with the ball in still water, put some weights in order to make it submerge( just enough to make submerge, not too much weight), then put it on the vaccum chamber. The ball will floats again, overcoming the action of the weight.

It doesn't look like a game of pressure. From what I see with this experiment is that the volume of water level remained same whether the ball was inside or outside. It seems that extra empty volume created below the ball kept the ball up. Since the volume below the ball may not be air due to vacuum chamber, it means there is simply not enough space for ball to sink in the water. Also because the air is sucked out, the density of water should increase which should also contribute for ball to remain up in the water. Can we do this experiment with just the water(without air)? This is definitely centrifugal force which created low density area in the center of water but when we removed the air from water, the density was increased again and ball moved up.

6:55 One unit of atmospheric pressure is completely arbitrary, so if lower pressure causes it not be pushed down as much, then yes higher pressure means it's pushed down more. Pretend we consider 0.5 atmospheres to be "normal", so you did your experiment on the range of 0.1 - 1 atmospheres, up to twice "normal". In the range of 0.5-1, you noticed "higher" pressure pushing it down more.

Cool experiment. The "fast moving fluid" thing is definitely true - and it has a name: "Venturi effect" And why no mention of centrifugal force? What happens when you spill your sippy-cup on the merry-go-round? Convection currents? I bet you could pump that ball down into a tube with a relatively small flow... Interestingly, that flow is what gives the vortex it's helical appearance. It's not just going around, it's going around and down. Vapor pressure of water, under vacuum? Well, you have a vacuum chamber, you should know this.
