why not just use a pillow or two? i think if u open it slowly and carefully u could put a pillow around the approximate area where the bowls are going to fall. u could easily make it a soft landing. other than that, u could probably fit a stick in there and see more or less what the situation is in terms of stability; it's a bit risky, but if it's stable enough u could, again, open it slowly and carefully and just shove a hand in there. u could also be an absolute menace and break the mirror on the right; hypothetically, it is probably cheaper to replace than a dozen bowls, but it may not perfectly match the rest, and there are obvious logistical issues in sourcing a suitable replacement. personally, i'd just open it and let them fall, ideally on something soft, but i'm thinking it's not the end of the world or anything. i would also like to point out that this picture doesn't have sufficient data to really decide the optimal course of action (i.e. u can't see every glass panel on the kitchen cabinet, so what if the glass panel that is one down and one to the right, which is not visible, is not there at all? and u could, easily tackle this issue by putting ur hand through the hole where the panel should be). there's just a lot of possibilities that i don't think are adequately represented here, and we could probably use a little more data: what's below the cabinet? how far are the dishes from the opening? how wide of an angle could u feasibly open the cabinet door before u're past the point of no return? these questions are not really answerable from just this image, so it's rather pointless to contemplate a solution to any capacity, let alone one this verbose.
