We all know the finger on straw works but I was wondering if I placed a stopper on top of a tube that had several honeycombs and put water in each layer would the water stay?

>> No.3650812

As long as you keep the container flat enough to not allow any air in it should work

No, because water can flow down the tubes on one side, and up the tubes on the other.

>> No.3651041

>>3651027 cont.
Whichever tubes have slightly more water in them will flow down, and the ones with slightly less will flow up.

And by tubes I mean the little honeycombs.

even if it was on a flat surface no air could breach?

>> No.3651065

why OP whats the point?

remove the honeycombs and it will function exactly like the straw?

>> No.3651086

>>3651050
You mean if there was a flat surface beneath the bottom, and air couldn't get in around the sides? That would keep water from flowing out of the bottom, but it wouldn't stop water from flowing through the two honeycombs in the middle. I don't think that was the OP's intention, though. I think he wants to have the bottom hanging in the air.

its for a bong, I did a better picture, there would be less drag and no chug if the water was already at each honeycomb

I made a better pic

it doesn't matter if some water drips to the bottom as long as it does loose all of the water in the system, the plan is to have about 15 high of honeycombs, as long as the pressure will reduce the flow of the water downward enough to make it viable to use.

can somebody explain this to me while we are at it

there is stopper on top so how the fuck

One-way valves, perhaps?

there is no valve

his other videos show the whole bong but that one best showed the percs

I want to use a one way valve with the honeycombs to achieve the same effect

>> No.3651247

>>3651165

multiple percolators

>> No.3651327

not a physics major but.

seems obvious, the honey comb would make zero difference to the pressure, so whatever level the water was at when you put your finger on it it would stay at, just like the empty straw.

nice image

i'm pretty tired right now and got lost thinking about how fucking amazing it is that we have devices that fit in our pockets on which we can store every song we've ever heard*

the things we use every day would shock and awe almost everyone in history, and even a lot of people living now in developing countries

fuck yeah, technology!

*too bad there are so many greedy fucks pushing for laws to restrict information and development in general for their own personal benefit
