7Up

7up is the brandname of a lemon-lime flavored soft drink produced by the Dr Pepper/7Up company in the United States (a unit of Cadbury-Schweppes), and by Pepsi outside of the United States. 7up was concocted in 1929 in Saint Louis, Missouri. It originally contained lithium. In the 1970s, an advertising campaign dubbed 7up the uncola.
