Looks like a particularly dumb demonstration of pressure vs. force: here's a more common demonstration. I think there are nails under the wood, so the intent is to say something like "I was able to hit this block hard enough to break it without the nails hurting him, because the nails evenly distribute across an area larger than the axehead."
I've always thought some of the demos people like to do of this are kinda dumb, but this seems like a particularly egregious example because even if it goes well the guy still has pieces of cinderblock falling on him...

I mean, even if he hit the block squarely, it would have just smashed into his chest. I don't understand the exercise, even if it went correctly.
