Studying its mechanism vis-a-vis the original image, perhaps Michellehihi is right and the jar is sealed tight. Uh oh, things are getting more and more dire for our heroine. Maybe only a deus ex machina can save her now. I hope the lid has air holes or something.
Of course I am right! We have those jars everywhere here in stores. I make my jams and canned spaghetti sauce in them. Let me tell you, when it is close, it is close tight! There's no way this girl will be able to open from the inside.
