I bought a bottle of 100 ml/ 3 mg flavored juice. I wanted 6 mg but the shop was out. The employee offered to make it 6mg with a flavorless nic additive. He put in 3mg and mixed It together. I’m a little confused by the result. Would it still be 3mg? Because this does not feel like 6 at all and I’ve shaken this bottle vigorously multiple times. I thought if you added the same number together, it would still equal the same amount of nic....
If it was 3mg/ml, and then he added 3mg/ml, it would be 6mg/ml total yes.
The only thing that could pose a problem is, the nic added takes up space and if the bottle was full, well there's no room for the nic then.
It would depend on if they just added some nic base ( e.g. 100mg/ml stuff ) or if they added a nic shot ( typically 18mg/ml ).
With the 100mg base, it would only take up about 0.9-1ml of volume. With the nic shot it would be 10mls. Which would mean, unless the bottle was a shortfill, that some liquid ( and thus flavor ) would have to be removed to make room for the nic shot.
You can normally fit 1ml in a "full" commercial liquid. Fitting 10mls is a different story.
>With the 100mg base, it would only take up about 0.9-1ml of volume.
Close, but the correct answer is ~3 more ml, for that 100ml bottle.
Not sure about your specific bottle, but adding the same number together would not give you the same amount of nic. You're thinking about it from kind of two different points of reference. Your bottle was originally mixed at 3mg/ml. You wanted 6 mg/ml. Those numbers don't represent a total amount of nic, rather an amount relative to the total amount of juice (nic concentration). So, if you added nic to a juice to get it to 3mg/ml, then added that same amount of the same nic, would not have exactly 6 mg/ml, rather every so less than 6 mg/ml because you now have more than the original total volume. Chances are what the guy did was add a tiny amount of a strong nic base to bring the total nic concentration up to just under 6 mg/ml. You can get to 3 mg/ml using any number of nic base concentrations. For example, you have your 100 ml bottle at 3 mg/ml. In order to get that up to "almost" 6 mg/ml, the guy could have added 3 mls of the nic base at 100 mg/ml. But like someone else pointed out, that's a lot of filling of an already filled bottle. Double the base nic strength and he only needs 1.5 mls, etc. The only way to add the same nic base as the current nic concentration and the result be the same nic concentration would be to double the total volume of the juice.
If he added flavourless 3mg/ml to your 3mg/ml then he just diluted the flavour. It would be like topping up your tank thats half full with the same eliquid. If he added high strength nicotine to your 3mg then it would mean more nic per ml in your bottle.
Think of it like alcohol. If you mix 2 whiskeys that are 40% alcohol together then you still have 40% alcohol in the mix. If you mix a 40% whiskey with coke using 1/4 whiskey and 3/4 coke you end up with a whiskey and coke at 10% alcohol content. If you mixed more whiskey into the glass your alcohol content will increase but will always be lower than the whiskey itself.
Hope this helps.
I came up with two amounts depending on what is added or subtracted to an assumed starting point of a 100ml bottle of 3% e-juice, and assuming a 100mg/ml nicotine additive.
1.) If the original 100ml bottle was simply added to in order to make it 6% strength, then it would require 3.36ml of nicotine additive. Because the volume is now 106.36 ml. At the original 3% it would have required .18% more additive and in order to arrive at 6%, .18ml must now be multiplied by 2: thus, .36ml.
2.) If the original 100ml bottle was substracted from, 2.91ml would have to be removed, then fill it to 100ml with the nicotine additive to arrive at a 6% solution.
I can't say if this is correct. I used an online calculator at e-liquid-recipes.com.
