The next revolution in sucking power after the Flex-Straw was this product that I made my mother stockpile so I’d never have less than a month’s supply. Though chocolate and strawberry were my favorite flavors, the success of mixing the flavor with the liquid you were drinking depended on the sucking power of your cheek muscles as the granules or whatever it was inside – some people remember it as a chemically soaked felt strip – oftentimes clumped leaving one with no other choice but to rip the straw open and dab bits on your tongue as you drank. Whatever the contents,  process or the amount of effort it took, I still enjoyed the personal power I felt over relieving myself of the tedium of milk.
