No, I do not want to suck light....that would be useless to me unless ofcourse I could alter dimensions ]

I have come up with a design for a suction cup, I am not sure whether these exist already or if I have to make them myself. If they already exist what are they called? If they dont exist what kind of material should I use to make these little windows inside the suction cups? This will enable me to keep the suction in one cup strong even though the pump isnt sucking anymore in that valve.
