I went to my first Anime Convention this weekend (that's a whole other story) to meet a guy I'd been chatting with and saw a girl rattling a really cool looking bottle. The gentleman that my date was, he went out and bought me one so I could have the Ramune experience too! Ramune is a soda that's been sealed with a marble and often comes in a cool bottle with the sides squozen in. Sounds new and nifty, but it's actually been around for quite a while. The pressure of the carbonation keeps the marble in place, and only by using a special tool that comes with the drink, can you open the bottle. The soda was so-so, but the bottle is so cool looking. There are people who try to get the marble out, but personally, I think it looks cooler with the marble in. Next time I get a bottle, I'll keep it sealed because the glass looks nice with the colored liquid inside.
