I bought a marbles edition Orb (I work at marbles the brain store). I got it open, but now I have a big problem.
I was very proud of myself, and showed it to my younger sister, who promptly dropped the ball bearing into the lower half of the puzzle and closed it. I do have the key itself out.
Now, it will not open at all, although the plunger works. (It's effectively dead-bolted shut.)
What do I do?
