experiments!...
This time my cannabic vapour path doesn't include a mixing bottle where to inject moisture. Instead, that bottle has been recycled in order to implement an
uni-directional valve, so that it becomes impossible to blow fog into my HerbalAire via its glass accessory (Arizer Solo). I could as well have used just 1 single 5/16 " I.D. 7/16 " O.D. PVC tube in place of 3 joined sections, as long as it has a tiny hole down the curve to let the fog in while draining excess water out it will do great it seems...
We don't see it well under the dome (soft-drink bottle piece) but that tube bends down near the middle, above the reservoir handle. A pair of red wires (on top) attaches the dome to this handle for more convenience. The bended tube section passes over it exactly.
Now here's the valve, it's a multi-functional item meant to keep the mist where it's needed and more!...
Fresh air enters the bottle through the right-side brass connector which then carries that air under water via a "bubbling" tube. The air below the bottle's top will follow a long tube and feed the vaporizer via its pump connector, eventually.
Smoke-like movements in my glass stem become even more visible as a result of the bubbling turbulence created in the water inside my "valve" bottle during inhalations. As for the sound, that's a real nice feature all by itself considering that it provides a complement of bio-feedback!
So, briefly put i'm now mixing cannabic vapour with fog
within the inhalation tube itself. The humidifier's tiny fan doesn't generate enough pressure to pump water out of the valve bottle, though that pressure is sufficient to ensure that the precious molecules stay trapped inside this tube.
Moderate inhalation only will supply fog alone. A stronger effort forces new fresh air to enter the system, pushing the vapour load ahead. At 1st i inhale faintly to fill the dome, then more intensly to fill the path with my favourite type of vapour...
Then the next inhalations reveal taste & aroma in quite a pleasant manner.
A sliding piece of tube covers the mixing hole partly, enabling me to adjust the amount of fog to be inhaled with my vaporized load. It takes only one hole and it doesn't have to be large (equivalent to 1/16 " or so); when set correctly there's very little thinking to do, except enjoy and hence notice that the disturbing coughing urges are gone for the most part!
Inhale, enjoy: that's simple enough as a proof of concept. I could have done it using no hot glue at all, as a matter of fact!
