I've searched the forum in vain for an answer, but I've come up empty. I made some juice tonight in a 10ml bottle, one that originally held a vendor liquid marked 10ml. I measured out the ingredients and it only filled half of the bottle. I double checked with two juice calculators that I entered 10ml for the amount I wanted to make, and I KNOW I put in the correct amount of base (8.33ml), VG (.66ml) and flavoring (.10ml) . I made another batch in a new purchased empty 10ml bottle (although a different shaped bottle), and it filled it to approx. 3/4. I know it's late and all, but what the heck could I have done wrong (twice)?
