The following video demonstrates the effect of air’s compressibility on a liquid drop.
Air can be compressed into a solid, but air is not a solid. The difference is that the solid is more compressible than air, so the air will be forced out of the solid faster. As you lower the air pressure, the air starts to spread out, and as it does so it will begin to spread out at a slower rate.
This video uses the popular “Lipstick” technique to create a drop of air into a liquid. Instead of throwing the drop of air into the liquid, the liquid is dropped into the air and then the air is forced out of the drop. But the air may still be pushed out of the liquid and it can still spread. You can see the drop in the liquid on top.
It can also be used to create a foam surface for your air hockey game where you can press a small amount of air into a liquid. The air then forms a bubble around the air that you can then drop a tiny bit of liquid into to create a foam. This is a fun technique, but I think you should use it only as a last resort.
While the air has maximum compressibility, the air in the air hockey game is still too much like water. It can’t be compressed. The air is a fluid and the bubbles it creates in the liquid are air bubbles. Therefore the liquid must be compressible so that air bubbles can be forced into the liquid.
In a way, you can demonstrate this by putting a large bottle of water on a table and pouring the liquid into the bottle. The result will be a liquid that is only a tad less dense than water. If you drop an atom of air on the surface of the liquid, the air will bubble into the liquid and create a bubble. Since the air has a compressibility greater than that of water, you can then use an air-filled balloon to demonstrate that it has maximum compressibility.
To demonstrate your new understanding of air, we’ve added a few more things to my list.
Air bubbles are actually the result of a complex process called thermodynamic bubble nucleation that happens when air is put into water. The two sides of an air bubble are liquid and gas, so when the air is put into water, the two sides become the same. And since the air bubbles can be very small, they can be extremely difficult to see.
When I write this, I have to mention that the reason I’m using the word “bubble” is because I am a fan of the word bubble. So, this is a pretty good description of how bubbles can be created. We will cover how bubble nucleation works to show you how it works.
So, you’re going to need a good camera to see it. That’s because the way the air bubbles are made is that the air bubbles are created from the bottom up. At the air bubble’s bottom, there is a liquid that can’t support itself, and the air bubble is simply going to grow horizontally. The air bubble grows until the liquid at the bottom is less dense than the gas above it, and the liquid is pulled out as a gas bubble.
