or is it just for looks/comfortability? I see reducing sections on a lot of RooR's and I hear things about bore size having to do with the speed of the clear and the quality of the hit. Does the reducing section on RooR's do anything practical or are they strictly for an appealing look? Here are some examples. I'm asking about the "Wavy" section of the tube. http://www.grasscity.co.uk/img/products/terminator_s.jpg http://www.grasscity.co.uk/img/products/roor_custom_3.jpg discuss...
im pretty sure its for your hand, and for looks, and no it does not affect the clear or the drag, the reduction is pretty minimal
Indeed, it's just a grip... go look at an icemaster and you'll see why that's convenient. Doesn't effect anything.
yeah id say thats for aesthetic/comfort purposes only. but i really dont have anything to back that up.
Me too... I've always assumed it was to make the tube ergonomic. They also can hold ice on tubes without pinches I guess.
You are refering to the "narrowing section", at least thats what roor.de calls it on there websight. When i custom ordered my .de i did not order the narrowing section. To make a long story short, they ended up putting 1 on it anyway. You can get 2 on certain models i think. The narrowing section is totally functional for grip, and now that i've used it, i won't get another bong of this size and weight(got the lil sis 5mm) without. When i use my ice notches, the tube gets super slick w/ condensation, and im sure either i, or a friend would drop it eventually. But with that section, and the ice notches above, it stays dry for a solid grip.
I really do like the reducing sections....like the person above me said it's great for your grip! Not to mention the smoke looks pretty cool when going through the narrowed sections. Also i'm not sure if this is true or not, but i think maybe by increasing the glass surface area it allows the smoke to cool more quickly? Anyway, great looking piece above ^
if it had anything to do with it scientifically if forces smoke faster through the neck. remmebring from high school....venturi effect? liquid/gases will all try to go through smaller areas at quicker speeds...ill look it up after this post
^ awesome post. Thank you. edit- lol look at the highschool physics project photo on that page....think of that except all glass with a roor logo on it. Mmmmm
yeah from the example i remember from my class is a hose. if you cover half of the opening, rpessure builds and the liquid all tries to go out the smaller hole at once, creating a larger stream.
Werd. So there are definitely some effects on the milk with a narrowing section along with comfortability. Thanks for the info mang!
Reducing sections are used a lot to make the tube clear faster. That is why a lot of high end artists are starting to house their percs in 55,60,65mm and then reducing the bore to 44 or 38. For any well functioning tube, a fast clear is essential.
If you think about it, though, once the tube becomes un-reduced and of the standard bore, I don't think the venturi effect plays any role. Yes, if you had a greatly smaller bore throughout AND pulled the same amount of air (soon smoke) through your bowl, it would go faster. I'm willing to bet however that this is not the case when a reducer is only temporary. The extra pressure will just go towards filling the larger bore. Someone back me up here, but I think I'm right. UNLESS: The percs are in a larger bore chamber for better functionality and THEN the ENTIRE bore is reduced. That is the only practically effective that seems logical.
i think Jarhead is correct, i was going to say the same thing because thats how it works on mine. Because the tube opens back up to a larger diameter, it diffuses the sodastraw effect. I don't think i've ever got water on my mouth because of that.
