A clear acrylic casing and a slow-motion camera show you exactly what’s going on inside a gun suppressor.
A firearm suppressor is a complicated piece of engineering that works by containing the high-pressure gases and exhaust when firing a bullet. If those gases have nowhere to go, they can’t create shockwaves in the air and produce sound. But as you can imagine, keeping high-pressure, high-temperature gas contained is no easy task.
There are many different types of suppressor design, but because they’re often enclosed in a metal case, it can be difficult to study them or watch how they work. That’s why Destin Sandlin from Smarter Every Day teamed up with Soteria to film some see-through suppressors in super slow motion. Watch what happens inside a gun suppressor in the video above.
Every suppressor has two parts: a large volume to hold expanding gas and a mechanism to keep it from escaping its container. Sandlin tested multiple different suppressor designs, but they all work in the same fundamental way.
It’s too bad that the acrylic used in the video isn’t as strong as standard metal—it would be nice to use a clear suppressor all the time.
