Suppressors are devices that deaden the noise that would otherwise be loudly heard when a bullet is fired from a gun. First patented in 1909 by Hiram Percy Maxim, they work by trapping the explosive gases that propel the bullet from the barrel of a gun after it is fired and the sonic boom that accompanies it.
SmarterEveryDay's Destin Sandlin worked with modern day suppressor manufacturer Soteria to visualize what happens inside a suppressor to better understand how they work by using a see-through acrylic sleeve on the supressor and firing several while filming with a high speed camera. You can learn a lot of engineering (and about engineering) in a short period of time from the footage of the bullet moving through the modified suppressors (HT: Core77):
The son of inventor Hiram Stevens Maxim, who had invented the first fully automatic machine gun some three decades earlier, Hiram Percy Maxim was an early automobile industry pioneer who would also apply the principles of his firearm silencer to that industry through his invention of the muffler for gasoline-powered engines in 1913.
