For that matter, what are people doing keeping your potions in glass bottles anyway? Or even earthenware or waterskins? Put it inside gelatin, or a nutshell, or a ball of resin/sap, or a dried sausage, or a bundle of cotton, really anything you can safely and easily toss in your mouth, bite through, and either swallow or spit out afterward as needs must. Putting it in a bottle you must uncork and swig from is insanely inefficient.
