Hello all,
I gotta call bullpussy on carbon filters. Thats just too much to believe...further filtering does what? Keeps your bong clean.
Well, I am sorry but I think its just marketing....again, why would you filter your smoke...that which gets you high is just adsorbed. The taste, a product of turpines (sp) and flavonoids (sp), that you so blattently ascribe as being superior are also filtered out.
And while I am at it, and not to blow my own bong, but I am an engineer also and I can tell you that your diffussor mearly aids in further filtering by increasing the total volumatric surface area. That is, 10 1cc bubbles has more sruface area then 1 10cc bubble.
I find these things to be counter intuitive. My bong has water in it simply to filter the ash and cool the smoke. I want to do this without removing that which I am smoking it for in the first place namely the THC.

(Minds_I - did you ever do any kind of chemistry when training to become an engineer? Just wondering. It's cool to assume that all of the constituents of pot smoke might be all filtered out equally, but that is not the case.
Who's to say which molecules are filtered out in which concentrations? Have you heard of a mass spectrometer? I don't know the answer as to the ratio of carbon monoxide and other nasties to THC in their adsorbtion to activated carbon - it could be 50% of THC sticks to the filter vs 10% of the tar/nasties, or it could be the other way around. It depends on the relative molecular mass of the molecule.
So it's not as black and white as it seems. If it turned out to be something like you lose 10% of the THC from a bowl, but 50% of the tar - that could be a good thing and not too bad a sacrifice. But who knows - could be a marketing gimmick - but it has some science behind it.
If you'd like to know more Activated carbon and Chemisorption.
But I digress.)
I really wanted to know what people think of ashcatchers - was thinking of getting one - any designs that are more functional than others?
And what type of bowl is best to use? I've got a bowl shaped like this with a glass landmine thing inside.

What type of bowls do people use for hash?
And also favourite length of bong? Short or long?
