I would have just told people to go look it up or something.

Physicist Andreas Wahl wanted to demonstrate something we already know, that water is denser than air. Rather than busting out with a bunch of charts and graphs or any boring old science stuff, Captain Drama shot himself. (This isn't the first time he's done crazy experiments.)

He put a loaded rifle into a pool, tied a string to the trigger and actually shot himself to demonstrate this density thing. It seemed to me that this guy's a little dense himself to think the air/water density difference was enough to slow a bullet to non-lethal velocity. It didn't just slow it down though, it pretty much STOPPED it!

The next time you see some Hollywood action hero blasting away underwater, feel free to call bulls***.
