AK-47 fired underwater is frighteningly beautiful
Gun fanatic or peacenik, you’ve got to admit that this video showing exactly what’s happening when you shoot an AK-47 underwater is insanely cool. Listen up as Destin fires off the weapon in a swimming pool in Alabama and proceeds to impart all sorts of higher knowledge while we soak up the ultra-slow-mo action. Put together for his SmarterEveryDay YouTube channel with help from the Slow Mo Guys, this is where you’ll learn all about the Rayleigh-Plesset equation, Bernoulli's principle and sonoluminescence. If physics class had been this much fun, we’d all have become science nerds.
