Is it possible to simulate air pressure in blender? (Heron's infinite fountain effect)
Hello guys I would like to ask if it is possible to simulate Heron's fountain in blender? I am not sure if all of you are familiar with this one but it is like an infinite water fountain loop that is ran by the physics between water, air , and gravity.
Thanks.

Yes, use molecular with two different particle systems and for rendering hide the one used as the second fluid (air), it will probably work.
* @Juan Gea Rodriguez * I guess that would be the right strategy to use. Thanks.
The video is a fake. The two containers are at the same pressure.
* @igiornotigi * I am not familiar with the science of gravity. But what about the first container? It tends to transfer its heavier pressure to the next container.
I think that would cause the pressure of two containers at the bottom different.
This diagram is freaking me out - If it's an infinite loop, how does Container "B" get refilled??
* @ammusionist * It is not posssible to refill container B. The setup displayed in the image will not be infinite because container B will ran out of supply because it is missing an important piece of tube which is added in the video.
A lab found a solution for this problem. The link is in the description
* @ammusionist * The tube that connects b and c is for the air pressure to travel. It is not for the water. This diagram shows the original attempt but it is not the solution for the infinite loop.
* @johnpdelacruz26 * The video is fake. It violates the laws of physics. But if you want to simulate it in Blender you can probably fake it there too :)
* @gbs * Can you explain why. In my opinion this is valid. It is air pressure that is making it possible. It cannot be literally infinite but you can call it somewhat close to it. There can be factors that can affect its effectiveness, one would be evaporation.
* @gbs * The containers should be tightly sealed from what I believe. Liquid contents should also be near precise and let gravity do its thing.
* @johnpdelacruz26 * The original finite setup is just mechanics. You move a large mass of water down in order to lift a smaller mass of water up higher. All the plumbing is uninteresting. It's just a lever. The infinite version is simply fake (there's an electric pump in there somewhere, likely explaining why the liquid is opaque).
