Paranormal wind?
I was kind of surprised when I saw people talking about paranormal wind. I guess first I would like to know how you would know it’s a paranormal wind? I also was surprised to see talk of using a firefly wind detector to test wind in an air tight location. None of us would ever investigate an air tight location unless of course some science center reported a haunting.
Every home and building we investigate will have air currents, there is no air tight location. Every time a door opens or closes air in the home moves. A person walking creates air currents in a building. Your home moves air every time a furnace or air conditioner kicks on. Homes have chimneys, these have air currents, a temperature difference outside a home will cause air currents inside a home. These same temperature changes occur naturally in homes with the basement being cooler then the upper floors, THIS CREATES AN AIR CURRENT! The direction of the flow depends on the temperatures. If inside temperature is higher than outside temperature, inside air density is less than outside air density, and inside air will flow up and out of the upper parts of the building. Cold outside air will flow into the lower parts of the building.
If outside temperature is higher than inside air temperature - the air flow will be in the opposite direction.
Did you know most places have small air leaks around electrical outlets, baseboards, dryer vents, pipe and cable penetrations, attic hatchways, and ceiling light fixtures. So once again first understand naturally occurring wind before you call it paranormal wind.
Now knowing this information why not instead of a firefly get a Thermal Leak Detector they can be picked up for around $40.00 then learn how to use it. Start by setting a reference temperature by pointing the device at an inside wall, and hitting the "set" button. Then scan the sensor along a surface. When it hits a cold or hot spot, the LED light changes from green to red (hot) or blue (cold). The surface temperature is also displayed on the screen.
How about you teams that are on a tight budget? You can detect air currents with incense. (just be careful not to burn anything.) Hold a burning incense stick around electrical outlets and baseboards to test for air flow that hurts energy efficiency. Such an air current will cause the smoke from the incense stick to waver in response. You can get more accurate results from such a test by closing all fireplace flues, windows, and doors, shutting off furnaces, air conditioners and water heaters. Now if your like me I can’t stand the smell of most incense so you can buy an unscented, 100 sticks for under $5.00.
So before you call something paranormal wind make sure the wind your catching isn’t naturally occurring.
