LiquiGlide is my dream come true, because it solves this problem, as described by the New York Times: “Much of what we buy never makes it out of the container and is instead thrown away — up to a quarter of skin lotion, 16 percent of laundry detergent and 15 percent of condiments like mustard and ketchup.”

Of course, the folks at the Times and Consumer Reports never saw how much toothpaste I manage to eke out of that tube. (LiquiGlide-slicked Colgate may thus be my wife’s dream come true, too.)
