Ninja (Noongari) smoke

Woke up with a congested nose and after a while the place filled more with smoke. I went outside and again found some tiny one inch tall volcanoes under the siding. After i flattened those, tried to air the room but i think dirty socks smell comes from the wind's direction. After about ten minutes, smoke (different, probably kratom) is again filling the room. Going to the park. Hospital alleys. Whatever.

9:28 They speculate differences in perception. To me it's obvious what's happening. To most, they don't understand what i'm saying. What tiny volcanoes? Have he lost his mind this morning, again?

Everybody living in a house in the US has at least on bathroom fan. Ever wondered where the air sucked from the bathroom goes? Behind the fan, inside the ceiling (upstairs floor) there is a 3 or 4 inch flexible pipe or hose (flexible during installation, actually it never moves, for decades after) that goes through an (empty) wall all the way to the top of the roof. Made of a thin aluminum foil, with a coiled wire to make the shape, or something similar. It is not one piece from bathroom to roof. Pieces are joined with duct tape. Tape in time becomes hard and sometimes most of the times the pipe will leak at joints, inside walls. More or less. In time it also builds inside about half inch of dust on the thin foil. That may backflow in your bathroom, depending. Vibration, air flow. Airflow leaking from other pipes from other apartments, building pressure inside walls and inside your pipe. And had lots of that. Until:

I put on top of the regular bathroom fan a tiny computer fan that works continuously at lower than normal voltage (about 6 volts instead of 12) and ensures at least it does not backflow as it did. When the big fan starts, air flows through the small one, accelerating it. When it doesn't the small fan pushes constantly a small amount of air. But even if it didn't, due to regular thermal flow (warmer air goes up), some air will bypass the one way valve in the fan's box and flow upwards.

During drying. Vast amounts of air are being sucked from inside the room and pumped outside. Regular houses have driers installed in garages or other special rooms. But if it's not the garages, will suck air from where inside the house.

Believe it or not. Main fresh air supply inside a house comes from under main or back or garage door, washing the sills of those doors, one of the dirties places inside a home.

But there is another source. Walls are not sealed in most American houses. There is a big half inch gap between the "drywall" and the floor, other gaps and cracks, around windows, appliances, cabinets, etc..

Air goes in and out the wall depending. Some air from outside will bypass the siding (especially at bottom or where the siding starts) and cracks inside the walls.

And here comes the diagram of thermal air flow around a house. Cold weather here includes during night, evening and mornings, where house walls temperature is higher than outside air. All passive, high science, low teck, ancient knowledge.It's all self explanatory. If you stick (during let's say a casual dog walking) something burning inside the ground close enough to the building (most of the "recipes" in Basenshukai, or the book of  ninja, contain saltpeter, that has oxygen in the formula, other oxygen locking chemicals, saltpeter was not available in Japan when the book was written, and burns underground) the smoke, due to the pressure created by the laminar thermal flow will bypass the siding and the walls and get inside. Most of it will not get inside, but flow upwards around  the building and up in the sky and will not be perceived by bypassers. Since build up of concentration inside is gradual, the occupants will get used and after a while will start to change mood, feel happy, worry free, forget things, take weird decisions, etc..

And if you open the main door, smoke will come out, exactly like if the occupants themselves where using it, for all bypassers to smell. You will have it in you system, clothes, etc..

I apologize if the post is not 100 well formulated and concise, i am under influence, big time this morning, cause they are behind and getting really mad as more of their secrets (and deeds) are being revealed, everyday and pushing it big time on me.

Had plans for this morning, wanted to order online OEM axles for the car, can't do anything, can't concentrate, afraid not to order the wrong ones.
