Can water drip from a capillary tube top? Perpetual motion? In a normal capillary tube (ex: tube A), where the water doesn't travel as high as the tube's height, h, the meniscus formed is "normal" (concave, as seen in tube A).
From previous posts, I determined that if the tube's height is lower than the height that the water can travel, the meniscus becomes less and less concave, and will become almost flat (as seen in tube B).
Furthermore, I learned that if the tube is bent downward, the gravitational force will result in the meniscus becoming convex (as seen in tube C). This force of gravity isn't strong enough to "pull" the water away and make it drip, because the force from the surface tension is greater. And this fact has killed many perpetual machines dreams. 
However, I began wondering, if many bent tubes were positioned so that their top ends are very close together, allowing the meniscuses (or menisci?) to touch (like tubes D and E, except many more), would the meniscuses combine to create a water drop that will become large enough so that the surface tension force will be insufficient to hold the water up? And thus the water will drip down? 
(Let's assume that the tubes are bent almost vertically down, so there is little chance that the water drop, if it forms, will attach to the outer edges of the tubes).
Any help is appreciated. Thanks in advance.

 A: Assuming that the gravitational field is uniform in the region of the setup, and that the tubes don't gradually deform, it is simply impossible to be perpetual, because the total energy increases over time, since some is lost to air resistance and sound and heat when each droplet falls. Precisely why it fails to run may not be worth investigating, much like what to do when the trisector comes.
Nevertheless, some things ought to be mentioned. The capillary action in the first place is driven by adhesion. That is why it is flat (not bulging upward) when the (straight) tube length is shorter than the reachable height. So when you bend the tube downward, it is NOT going to bulge downwards in the way you expected. If it was pointing perfectly downwards, it will be flat for exactly the same reason as before! If not perfectly downwards, then there will be an outward bulge at the lower part of the hole but an inward bulge at the upper part of the hole, otherwise the net force would suck the liquid back into the tube exactly as in the upright case! So you cannot 'increase bulging' by merging multiple downward-bent tubes.
