Did a youtube video to debunk a myth about "cardboard kevlar" - what some beleive to be as using several layers of thick cardboard to stop bullet penetration.

Yeah. I thought it was crazy too... but you should take a watch... kind of interesting what we came up with.
here's the overview:
In this video, we put 2ft of flattened desktop cardboard boxes to the ultimate test... to see if it can substitute for the mighty body armor that is Kevlar. Will cardboard holds its own? Or would you better off hiding behind a wall poster? Watch to find out! If your looking for shooting videos and pics of the shootout, skip to 20 minutes in the video. First 20 minutes is myself covering the topic at hand, outcome, ballistics, ammo, and weapons used.

Note: this was tested with corrugated cardboard (the usual type for packing and shipping stuff). There is non-corrugated, and some of the folks over at xcrforum.com have tested only a foot of it - stating alot more caliberzs actually failed to penetrate as well (awaiting video/photo confirmation of this though)
hopy you enjoy!
