I've cut the plastic top of a Ramune bottle to get to the glass marble inside.
Ramune is a Japanese soda, sorta like sprite, that's very popular w/ kids. The bottle is pinched in the middle and the soda is kept in by pressure on a glass marble.
You open the drink by using a plastic top to push down on the marble. It then drops to the center of the bottle and rattles around while you drink. The original bottles are glass, but some newer ones are plastic.
The plastic ones allow you to unscrew the top that holds in the marble. The glass ones require significant cutting and sawing to remove the top. I think I used a leatherman wave saw, ats 55 Merlin SE, 440V Native CE, and my PE Dragonfly SS to get the last one off.
The pic below is decent, but Ramune normally comes in a light blue bottle.
