My bad i did mean what i wrote, seriously: i imagined it, i built it, i used it and i also mentioned it on this board quite a few times... But nobody is listening. Would you like me to start a thread based on it too or will you get the picture if i re-post one - the same old one - again?
You don't have to control anything really, the mist stays in the upper champer of a bong and this generates an imperceptible positive pressure inside which appears to prevent vapor flow coming from the bag
without the help of a valve: cannabis vapor doesn't leave the bag and fog stays in the bong (until inhalation begins that is!); this whole simple contraption implements the valve action inherently, as a result of its structure i would say. Any bong will do, provided that the
Mist Maker "hockey-puck" like module can get inside actually... I havent seen a suitable conventional bong yet but i'm looking, this is the prototype:
I tested fog filtering on harsh (read "BAD TASTING", yuk!) ABV and this rendered inhalation manageable. Perhaps i need to explain something to you, i presume: i'm a former hashish smoker who was forced to quit the habit around 2007 because of the severe caughing my old favourite habit was causing. I didn't think there would be THC in my environment again, then vaporization gave me access to that again in February this year.
Do you need a review relative to fog filtering as well? Here it is: don't try it if you like, the loss is all yours!
ADDENDUM:
Here are the construction details i've posted to the attention of FC readers before - LOoooooooong ago:

That particilar thread wasn't a big success neither, by the way... I never heard of anybody caring to give a try yet!
Perhaps if it were 100 % glass, euh... My bad all right!!!
