The Isis Adventure

I played with my Isis now for about ten hours. I read the clues weeks ago here at the forum (luckily because I have no booklet).
So I suppose, that there are three BBs inside (Dropped it accidentally and it startet to rattle ). One is on top, where the plunger sits, two (or maybe three???) in the bottom half. I think, you have to move the topper BB to the middle and press the plunger to release the locking mechanism. So far, so good. It is no problem to get the topper BB in the middle. No clue how, just turning and shaking it a while and the plunger moves half way down. I assume I catch the BB with this procedure.
Now I have a problem with the lower BBs. I think there are two of them. In normal position (plunger top side) the BBs are just rotating. No way to get them into a steady position. Upside down (plunger facing downwards) I can make them stop rolling around. But I can't imagine what happened inside.
It seems that one BB is in a hole, the other one either in a bigger bulge or on a magnet. Because if I shake the Isis I can hear the BB moving, but just a very little and it stops immediately when I stop shaking.
If I press the plunger upwards, it moves just a little bit further in with a slight "click". But I can't open the Isis.
Also I turned the lower ring (the one opposites the plunger) in every position, but every time the same: A silent click, nothing happens. After that I have to hit the Isis fairly hard to get the two BBs moving again.
Is this the correct way or am I totally wrong???

Thanks for reading

You are so close.

Can't go telling you the solution, all I'll say is keep trying to undo it, you really are so, so close.

I am desperate! Got so far in a few hours and since then nothing happened, except:
-My hands are hurting pretty much
-My girlfriend threw me out
-I got blisters on my thumbs

I really can not imagine the last step(s). I can cleary hear the BBs got attractet by a magnet. There is no way to make them stop moving. I tilt the Isis in every direction. Most of the time the BBs just fell off. Except, when I tilt the Isis backwards (when having the placentas in front of me). I can hear the BBs fell off, but not much. The got instantly attactet, when turning the Isis back.
If I wouldn't know better, i would say it is sheer luck to open it. Avoid the magnet and press the plunger... perhaps you are lucky and the Isis opens...
But this can't be the solution...

Ha, Finally! It's open!!!

Now I'm gonna put my Ramisis into the oven... 15 minutes at 120°C... delicious
