Awesome to hear this actually working! I wonder if holding it upside down works best bc it grabs the coldest fraction of gas and causes the biggest temperature differential for the PIR?
That's my thinking. Most of the PIR aren't very impressive and they're just looking for that temperature change, it doesn't matter which direction. I actually wonder if maybe the paper trick works when it does because it moves the air flow from air conditioning around.
