Some high speed footage of an AK-47 being fired underwater. There are a number of interesting things here:
1) The bullets go *maybe* 5 feet, and seem to have completely blown their kinetic energy within 4 feet. This should come as no real surprise… humans are, basically, ugly bags of mostly water, and you’d hardly expect to fire though six feet of *human.*
2) The bullets tumble almost instantly
3) Bubble reverberation
4) Possible sonoluminescence (but probably not)
Lesson: don’t bother trying to shoot someone underwater with an AK-47 unless you are right on top of ’em
