Mick West | Mylar Balloon UFOs on Thermal Cameras - Hot or Cold? @MickWest | Uploaded October 2021 | Updated October 2024, 20 hours ago.
Mylar balloons often look unexpectedly hot or cold on thermal cameras. This is because they are highly reflective of heat. When you look up at them against the sky, they look "hot" because they are reflecting the ground and the sky in the background is very cold. When looking down, like in the "Rubber Duck" UFO video (which may or may not be balloons) then they look very cold because they reflect the very cold sky. In low resolution videos (like Rubber Duck), they look entirely cold.
