turns out the best way to get the marble out of a ramune bottle is to heat the hell out of the cap by boiling it and prying it off with a screwdriver. works a lot better than trying to pry it dry and is a lot safer too, don't bother trying to cut it either, it's just a pain. boiling it is way easier, you just need to wait for the water to boil. thanks youtube tutorial, it actually helped me out.
