NASA didn't invent Tang, but their Gemini and Apollo astronauts made it famous. (Kraft Foods invented it, in 1957.) NASA still uses Tang, despite periodic bouts of bad publicity. In 2006, terrorists mixed Tang into a homemade liquid explosive intended for use on a transatlantic flight. In the 1970's, Tang was mixed with methadone to discourage rehabbing heroin addicts from injecting it to get high. They did anyway. Consumed intravenously, Tang causes joint pain and jaundice, though fewer cavities.
