Ramune Soda Marble Purpose

Don't get us confused or you may be in for a big surprise. (Eel Wasabi flavor anyone?)

History of the marble inside Ramune Soda

First there was the cork. Then there was the cork. Then...there was still the cork?!

Until 1888, everything carbonated was made with a cork.

Corks are nice but they are leaky especially with carbonated drinks. (Think of champagne bottles)

The answer was English.

Not the language but a person named Hiram Codd who invented the Codd-neck bottle in 1870.

Corks leak, plastic and marbles don't. Ramune comes in regular cans too but remains largely in its iconic Codd-neck bottle. 

By the way, did you break the bottle to get at the marble inside? Congratulations if you did, this is the reason they invented the bottle deposit. 

Yep, it is not modern day recycling but rather that they wanted their marbles to come back home which is why they put a deposit. Anyone lost their marbles?

...So how are Ramune bottles made?

Ramune bottles start out as something like a lopsided hourglass with with a marble instead of sand.

Originally the opening is wide enough to slide a marble in. Then the glass is reheated.

Liquid is pushed into the bottle. Really Fast

The marble jumps to the top and gets stuck in the plastic.

This creates a perfect seal.

And now you are the proud owner of a new baby ramune. Take care of it.
