Goli Soda / Goti Soda

Goli Soda or Goti Soda is a popular carbonated lemon, orange, etc. flavoured soft drink sold in India since the late 19th century in a distinctly shaped iconic Codd-neck bottle. The pressure created by the carbonated liquid seals the bottle by forcing a glass marble up into the neck of the bottle where it snugly locks into a rubber gasket. Opening the bottle by pressing on the marble thus releasing the pressurised gas is seen to be a fun experience.
