Norbert Herzog and David Niesel look at the history of energy drinks, which in the early days contained radium, a radioactive metal that was used as a luminous paint for watch and instrument dials. Radium use is prohibited today due to the danger it poses. This column also featured in the Abilene Reporter-News.
