This video was shot on February 13th, 2021 during a cold snap our city was suffering.
We had a morning temperature of -37 degrees Celsius (-34.6 degrees Fahrenheit) during this experiment. These temperatures are definitedly at the bottom range of our camera which is rated to a temperature of -40 degrees Celsius.
Below is the YouTube video of the event. This time, rather than having an overlay of the thermal over the visible as we had done in our previous article, we put together a side-by-side video (or a diagonal side-by-side to be more precise). A good portion of the water immediately turned to water vapor, but some also made it to the ground.
Now for the interesting observation. As the vapor, or mini clouds, go over the trees and houses in the background, this does not effect what is seen through thermal.
Thermal imagery goes through these clouds. It is as though these clouds were not even there. Visible light of these clouds blocked the background and trees from view from our eyes and our normal camera.
Additionally, if you pause the video at just the right moments, you can see the hot water leaving the cup, but then it disappears as the cold weather does it's thing and freezes the water droplets.
We hope you enjoy this side-by-side view of this popular cold weather experiment.
