Mobius Glass

canj00digit?

All my days in a daze...
I can't find the perfect water line for my 65t. I tried like Mobius posted themselves in this vid...


Then I see other videos of crazy stacking but the water line is much lower.

:hmm:

That is insane stackage. And in a fucking massive can too! :)
It does seem there is plenty of variation between pieces. Someone here, can't remember who,
talked about going to a LHS and water testing & choosing between 3 Clear Matrix pieces.
He mentioned picking the best performing of the three.


@NinjaMindTriks, funny solution! :D
something in rezblock/nace seems to act in aiding bubble stackage as has been reported by many folks.
Definitely gives me more bubble action than plain water.

Does "stacking" actually do anything other than look cool? Seems to me that most of the benefit happens when the vapor first hits the water...
More bubbles + bubbles staying intact longer = vapor touching water longer. Something with hardly any diffusion will be harsher than something going through a stack of bubbles.

The higher the bubbles stack, the longer the vapor stays in contact with the water, which should result in cooler vapor.

:hmm:

I fill my stereo matrix about halfway up the top matrix perc. That's been the sweet spot on both my 65t and 65b.

What you say makes sense but this is why i ask:

Q. Can I get a splash guard?
A. No. If you don’t like water in your mouth, choose a chimney shape. The bulb atop the frit in chimney models prevents bubbles from “stacking” so high they reach your mouth. There is no difference in function. The characteristic of the experience is developed where the bubble originates, at the frit. How far up the tube bubbles travel before breaking is strictly cosmetic. Stack height has nothing do with ease of draught, or the smoothness of smoke.

I'm gonna go out on a limb and say that's wrong :uhoh:. More/longer contact with water = smoother vapor. That seems logical. If the FAQ included an explanation as to why it makes no difference rather than just declaring it so, then I'd maybe give it some credit. But it didn't, so I don't. I'd be curious to hear an explanation though.

From Wikipedia:

The diffuser serves the primary function of cooling the smoke and combustion vapors that pass through it. The surface of the bubbles come into direct contact with the water, where the temperature difference causes an exchange of heat between the hot smoke/vapor, and the cool water. The tree percolator design incorporates a number of small openings instead of large singular ones in order to diffuse the smoke into a larger number of smaller bubbles. This serves the purpose of increasing the surface area of the smoke that is in contact with the water and increasing the efficiency of heat transfer.

That part isnt in question. Of course as the bubble travels through the water reservoir it gets cooled down and conditioned. Im sure more diffusion will break the vapor up to even smaller bubbles, maximizing the surface area that contacts the water and thus increasing the cooling/conditioning effect.

However, the question is whether or not this action continues as the bubble travels up the side of the tube.

I find it very plausible that there is such little water trapped along with the bubble that any additional cooling would be negligible.

Any vapor trapped in a bubble is not stationary, it moves within the bubble, so the longer the bubble stays intact, the more vapor comes in contact with the surface area of the bubbles. Because of this it seems logical to me that when a piece stacks higher, the bubbles stay intact longer so the vapor is cooled more. I'm not a scientist and never took fluid dynamics so I could be wrong but like I said it seems only logical to me.

As I said though, id think that the amount of water trapped within an individual bubble could be so minimal that those extra few seconds of being intact on the chamber wall would be irrelevant.

I tend to agree. It's minimal I think.
All things being equal at the point(s) of diffusion, I think the distance the bubbles travel makes a negligible difference.
While I love my Mobius pieces my favourite piece is actually my Joel Halen dual chamber... it has half the points of diffusion that Stereo Matrix does, and doesn't stack nearly as impressively (albiet in it's much shorter chambers), but I like it better, and it's not close. It's probably the dual chamber vs single chamber thing I would suppose.

Like you guys have been said, contact time with the water is most important and for that you cannot beat a recycler obviously.

I've been thinking I'm not sure I'll ever buy another major piece of glass that isn't a recycler.
I think I might be on the verge of developing a minor case of 'PhotoRider Disease'... only a much less classy, white trashier version. :D

I believe bubble stacks are mainly visual. My reasoning is that stale water stacks to the top of my tubes while fresh water doesn't. My tubes don't hit any smoother with fresh water than with stale water even though it stacks twice as high which makes sense because its the same exact perc.

In engines and pc waterblocks water turbulence is much more effective at transferring heat to the cooling fluid than the rate of flow - not a direct comparison but close. Turbulence allows VXH products to pump out a seemingly endless stream of hot air.

Diffusion creates turbulence in the water and vapor therefore improving heat transfer by allowing more water/vapor to come into contact with fresh, cool water/vapor. Only so much heat can be transferred to the same water, especially when its a minuscule amount like the water forming a bubble. The more fresh, cool water and vapor that come into contact each other the more efficient the heat transfer.

If bubble stacks make a difference it is without a doubt negligible because the water in that bubble can only do so much in the way of transferring heat.

:shrug:What about this... If the vapor is trapped in the stack of bubbles longer, then there is less likelihood of the vapor turning into 'claim because it isn't really touching the glass. So the surface tension prevents the vapor from condensing on the glass. I'm not sure about that... I'm just sayin'.

Does anyone have an opinion of the Reti perc or the Matrix perc? Is the matrix perc really worth an extra $35?

I'm thinking about getting a mobius piece to go with my new underdog vape. This will be my first expensive piece of glass and want to make sure I get what I want.

I am attracted to the 60b and the ion with the matrix perc and wouldn't mind any help steering me towards the one for me. I'm concerned about the sizes of the bubs coupled with a vape. Is the ion too small, and is the 60b too big? I've heard some people say the ion was a little bit small to use with a vape and a larger bub would be preferred. I'm concerned the 60b will be too airy in comparison to the kind of hits I could get with the ion, though. And when I say "too big", I just mean is it not the "perfect" size, not is it too big to be usable. Vice versa with small. I've already been trying out different sized bongs and bubblers with my pup, but I'm not sure what I prefer yet.

I understand this is all subjective, but I love hearing people's subjective opinions on it, I guess. Thanks!
