      The gun is likely a laser. White doesn’t absorb much light, but black does, so the laser is passing through the white balloon without it heating significantly, but the black balloon is popping because it’s absorbing the light and getting hot.

      Does anyone know what is actually being shown here?

      It demonstrates how color and opacity affects energy absorbance from light of a material.

      That is a hair removal laser by the way. You do not want it to deposit energy into the skin, which means it works best for light colored skin with black hair and worst (not at all) for dark skin with white hair.
