Ramune

(FYI: I put it at top value for money because in Japan, it's cheaper than a kinder egg! Over here, to have it improted costs about £2.50)

This drink is delicious! It's like lemonade, only sweeter! It's so refreshing, and makes you feel quite cheery, because of the fun of drinking it! The bottle has a marble stuffed into the top of the cap, which is held there by the pressure of the fizzy drink gas! It comes in an attractive glass bottle, with a pinch a third of the way down that stops the marble sinking to the bottom, and a couple of nodules that catch the marble after you pop it into the bottle. (these only work if you drink it at an angle)

It comes with a plunger that you take the safety ring off and use to push the marble down.

Honestly, an excellent drink!

(good for you too!)
