Caption: As the compressed gas is released its temperature drops below room temperature. Despite the name canned air, the can actually contains difluoroethane. Thermography is a technique for visualizing the temperature of objects by recording the thermal emission at infrared wavelengths. This video was acquired with a specialized camera that is sensitive to electromagnetic radiation in the wavelength range of 8 to 14 micron. The camera produces 320x240-pixel frames where different colors correspond to different temperatures.

Release details: Model release not required. Property release not required.
