Oh FFS.... I can't believe I read this whole thread. There's something like 100,000 different recipes and combinations of ingredients. Just shake the stupid juice once in a while.

Of course, the best post would have been:


sfgiants, evilfrog and critter man are a close 2nd. lol

Osmotic pressure??? Could you tell me what's the connection between osmotic pressureand our main subject?

There is none; I was simply saying we're talking about apples and oranges comparing salt in saline solution to ejuice

I'm not a chemist so I'm going to try and take advantage of your knowledge here. Please correct me if any of the following is wrong. PG and VG are our solvents. Wikipedia (not my favorite source but here we go) says of Glycerol "It is also used as a substitute for ethanol as a solvent in preparing herbal extractions." I popped over to the ethanol page and it says "The polar nature of the hydroxyl group causes ethanol to dissolve many ionic compounds ... Because the ethanol molecule also has a nonpolar end, it will also dissolve nonpolar substances, including most essential oils[20] and numerous flavoring, coloring, and medicinal agents." If VG was analogous to ethanol we shouldn't be seeing the separation, should we?

You'd have very similar situation if you mix a small amount of oil with VG/PG.

Oil wouldn't act this way in ethanol, would it?

Unless they're at concentrations that simply exceed the VG's capacity for them at room temperature. It's highschool chemistry stuff to add a solute to water (a solvent) at boiling point and then see some of it precipitate out as the solution cools. Perhaps that's what's happening with our juices? In this case I think we *would* benefit from shaking, or else some fluid of a bottle would taste stronger than the rest depending on how much excess flavoring is simply suspended by chance in each drop.

We should be able to test this. If you put a drop of food coloring in a glass of water and don't shake the beaker it will eventually diffuse in the water. If you put one drop of colored flavoring in a bottle of VG shouldn't be a saturated solution and we should see the color slowly diffuse

I gave up atty. You can lead a horse to water but, you can't make them shake their juice

I think its like the practice of tapping a pack of cigs lightly on one's hand or wrist before opening the pack. I think idea was to pack the tobacco a little closer in the cigs. Made for happier smoking. A little shake on the bottle makes for a "tighter" juice that makes a vaper happier. (If one rolled their own in the prior life, maybe a lick of the juice bottle before replacing the cap is better than shaking?)

OK 3 words. RIMP wins so far (her sig and emoticon don't count).

LOL @ JW50

I'm serious. You can answer this whole thread with 1 word in one reply. In fact, the forum will even make you put "......." after it since the correct answer is only 3 letters. It was a simple and innocent question, really..........and well asked too, I might add.

Please see the "How many ECF'ers does it take to over complicate screwing in a light bulb" thread.

I planned to just answer "yes", but the ten letter thing made me add more :) I'm surprised nobody has worked in a plug of their favorite mod.
