29. Q-Tip

Year Invented: 1920

Designer: Leo Gerstenzang

By sticking cotton balls on either end of a tooth pick, Leo Gerstenzang invented the cotton swab, or as it is most commonly referred to, the Q-tip. Gerstenzang originally named his design "Baby Gays," but it was renamed and marketed as the "Q-Tip" (the Q stands for quality).
