AK47 Firing Under Water
Will a gun fire underwater? Dustin from "Smarter Every Day" asked the question. To sweeten the deal he used an AK-47 and filmed it in super slow motion at 27,450 frames per second.
Guns are fully mechanical devices. The fluid that they operate in changes the mechanical resistance somewhat but they are generally unhindered. The footage taken in this video is really beautiful and worth watching. A surprising result even happens when the collapsing bubbles seem to magically re-expand due to oscillating shock waves.
