Turn air from invisible to visible! This is a diy "Schlieren Imaging" setup, and scientists use it to understand how air moves. Light rays usually move straight through the air, but when the air's density changes (like from heat), the light bends! Using a mirror, we can reflect that bent light into our camera and actually see how air density changes.
