Shake the Juice?

It's a good idea to just get in the habit of doing that because you don't really know which juices need shaking first. It sure doesn't' hurt if you don't but you might find that some juices taste better if you shake them.
As far as I know shaking doesn't take too much time. Maybe this wouldn't make a big difference but still it helps to make this mixture more homogenous.
My wife always reminds me to shake the orange juice or the milk before I pour a glass.
But she never says anything about the nic juice, so I guess it's not necessary.

I shake my bottles before I use them every time. It cant hurt it and it makes sure the juice is consistent all the way to the last drop.
Makes sence most liquids have both PG and VG in them and since VG is much thicker it would make sence if there is any chance they would separate .
They wouldn't. Mixture containing PG and VG stays homogenous. The process responsible for this is called diffusion. If it separates, something else is involved.
Definitely shake your eJuice before using. It only takes a few seconds.
If you ever made your own eJuice, you know what I mean. While adding different ingredients you can see that they have different weights particularly VG, you can see it go right to the bottom.

Specific Gravity is a term used to compare the weight of a liquid with water. Water = 1. Of course I used A-1 sause for years before I read the label that said to "Shake Well". ;-)
Probably wouldn't hurt but I don't bother. Why? Because the ingredients in the juices are soluble in each other so they won't separate. I wouldn't shake saline solution either for the exact same reason. It wouldn't hurt, but it makes no difference.
This has not been my experience. I also don't believe that saline solution and ejuice are analogous. Salts are chemically drawn to water; the osmotic pressure it creates is an everyday requirement of probably every living thing. I think you could compare the two (saline vs ejuice) if we're talking about PG dissolved in brake cleaner, lacquer thinner or some other strong oil solvent but ... PG and VG are our solvents. We're hoping that the coloring and flavors used are freely soluble in PG and VG and often that PG and VG will mix freely.
I shake my juices because it's visibly obvious with many of the flavors that they need it. VaporBomb's Cinnabomb is the extreme in this case. The Cinnabomb separates after a few minutes into three distinctly colored horizons with 100% VG: a brown, an orange and a yellow (brown on top). A quick shake actually emulsifies the solution, turning it a bright milky yellow. The Cinnabomb 2x is plenty strong enough; I dont want to try vaping the precipitated cinnamon flavor strait!
After some hard mixing (shaking) of certain clear 50/50 VG/PG juices I can usually see in the nozzle separate 'bubbles' of juice that look like a bunch of cells being pumped out of a tube. I'm not talking about air bubbles. The juice forms a membrane. I don't know if its flavoring on the outside (membrane) and 50/50 on the inside or simply VG and PG not mixing
This isn't visible with most of my flavors but I can only see so much with my nature-given equipment

No - specific gravity has nothing to do with it. If the e-liquid separates that means that at least one of the ingredients is not fully soluble. It might form an emulsion or suspension.
If you mix VG and PG (without any additives), the mixture will be perfectly homogenous, despite the fact that the difference in density (specific gravity) is approx. 25%. It's quite similar to the mixture of water and ethanol, even the ratio of densities are very similar. And no-one has ever seen a bottle of vodka with separate layers.
So if, for example, a vendor had mixed a cinnamon flavor and it separates into distinct looking layers within a short amount of time of just sitting around, does that mean said e-liquid has cinnamon oil in it?
Osmotic pressure??? Could you tell me what's the connection between osmotic pressureand our main subject?
You're right - salts are drawn to water, but the mechanism is rather physical, not chemical. The key word is "polarity".
Believe me - PG and VG mix freely - in any proportions. If you don't believe me - make an experiment.

The effect you describe here shows clearly that flavorings are at least partially non-polar, so they don't form a real solution with the solvent (VG/PG). You'd have very similar situation if you mix a small amount of oil with VG/PG.
