  bubblesand sold at soda fountains. Untold
  billions of Cokes have been consumed since then.

  decades, every truly big city had one.

Which came first?

• Instant PhotographyWhen his daughter asked why
  she couldn't see a picture he had just taken,
  Edwin Land began working on an instant
  photography system. His solution, worked out over
  seven years and refined for decades, sandwiched
  all the necessary chemicals into one sheet of
  photo paper. The first instant pictures were
  black-and-white and appeared in about 60 seconds.

• Instant CoffeeInstant coffee was invented twice
  first by a single chemist, then by the giant
  Swiss company Nestle. The chemist saw that coffee
  vapors condensed as a powder this powder could
  be mixed with water to make coffee. Later, Nestle
  sought to help Brazil find a market for its
  surplus coffee. The solution was instant coffee,
  freeze-dried, rather than powdered, and made on
  an industrial scale.
