Most of the bottles we get
eliquid in have dropper caps that pop off fairly easily. If you have used up even a couple ml off the too-high-nic bottle, push sideways on the dropper tip and it should pop off (even simpler, truthfully, is loosen the screw top and, after the top has cleared the last thread, just push sideways and the dropper should pop off, be sitting in the cap).
If you cannot pour from the glycerin bottle into the partially used up
eliquid bottle, get an oral syringe -- they are very common, used to provide meds to babies, ask for one at the pharmacy desk and they shouldn't be too surprised. Just tell them you are looking for a small oral syringe. Pull some VG up in it, squeeze it into the bottle, then recap the bottle, shake and vape.
Try a canadian version of a dollar store, look for a tiny bottle of food coloring, empty, rinse, and you will now have a spare mixing bottle
