Q&A for How to Open and Drink a Bottle of Ramune Pop

It doesn't have a cap, so the closest you can get to 'closing' it is saving the plunger and using that to plug it. You could also use a piece of saran wrap or tin foil to close the top.

You don't. You just drink it with the marble in there; don't worry, you won't choke!

You may be able to put enough pressure on the marble with a digit to be able to release it. However, I would advise using a similarly shaped item (circular with a hollow centre) to replicate the bottle opener included with the pop.

Yes, it's carbonated, the marble inside the bottle is designed to maintain this because it has no bottle cap.
