I just started reading the 2nd part of Jim Humble's book today. I previously had questions about whether to get a separate dropper or try to shake drops from the spout on the Miracle-Mineral-Supplement bottle. I just found some information that helps me and may help you. In his book, he states that a drop from normal glass droppers that go sort of in a point at the end are only 2/3 the size of a drop from the packaged bottle. I have absolutely no idea how you can get 1/2 a drop, either, but you may want to purchase a glass dropper. At least you would be getting 2/3 a drop that way.
