Watch The Shock Waves Made By Different Guns

Schlieren photography lets us see the interference patterns in light created by the different densities in the air that the light passes through. This video uses it to let us look at the shock waves given off by different guns.

What you see is what you get with this one. The Splash Lab, which usually works in fluids, takes a look at the disturbances in gas when guns are loaded with blanks and fired. We see a pistol, a rifle, and a shotgun. I’m not a gun person, but apparently the pistol and rifle both have spiraling grooves cut into the barrel, making the bullet less likely to wobble.


As for the shotgun, it looks like there are two outpourings of force. The first looks like just gas, and the second looks like solid matter. Anyone with more gun experience or knowledge want to weigh in on the video, the interference patterns, and what it tells us about the gun we should use to survive the zombie apocalypse?
