Shooting a gun under water

The slow-mo guys record bullets fired underwater with a super high speed camera.

here's another video of firing an AK under water too.

Now that's pretty wicked. I would almost like to see high speed footage of shooting a firearm in the weightlessness of space. I have seen where fire fires in a spherical shape due to no gravity, I think. definitely cool footage shooting under water though. thanks for the link.

The 2nd video is excellent!! This young man's video stands much higher than simply firing a gun. I will show this video to my son, hopefully, one day he would build some interest in science.
