yea i see what you mean , except i was thinking the water that has exited the cups can flow and collide with other water exiting other cups and so on , and maybe create abit of back pressure on the water exiting cups and deform the jet. thats the main thing i was thinking about when i thought of this .
how to ensure ther was no water trying to flow back down into the cup and deform the water jet at the bottom by hindering the flow.
