Undoubtedly, one of the shining achievements in portable children's nutrition technology. Little pills of different colors, each shaped like characters from The Flintstones (a grinning Dino, Fred giving you the thumbs up, Barney's Binary Four). Follows the fake flavor-coloring correlation theory, so that the purple pills taste like anything but grape, and so on. Warn your child that inserting the pill into the nostril is not the optimal way of gaining vitamin-y goodness.
