Ever wondered why you can see a laser beam in mid-air? It’s all about scattering—light bounces off dust, smoke, or water vapor, making the beam visible. In a vacuum? Totally invisible unless it hits something. Brighter lasers = more scattering, and green beams pop harder because your eyes love that wavelength.
