Should you ever find yourself underwater and needing to fire your duty weapon, a former US Navy corpsman and firearms blogger has shown that it will work.
Andrew Tuohy posted a YouTube video that shows the discharge of a Glock 22 underwater, with the results being shown in slow motion. According to Gizmodo, a Pentax WG-2 camera filmed the shot at 120 frames per second, which Tuohy slowed to 30 frames per second.
Dr. Louis Bloomfield, a University of Virginia physics professor, told the Huffington Post about the science behind the awesome video.
"What you're seeing is primarily a gas bubble created by the propellent gas from the bullet... The bubble essentially overexpands because of the water's outward momentum," he said.
"Once that outward momentum dissipates into the pool, the no-longer-hot, over-expanded propellent gas can't fill the void and so atmospheric pressure crushes the bubble to a much smaller size."
