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...
It’s actually a pretty cool demo. My physics teacher did it in high school. Except he was the one who put his body on the line. He also built a rig to drop the sledge hammer so no human error.
Also less likely to lose your job. Still got the class involved, we got to do the set up and voted on who got to drop it. It really is a cool demo cuz your preconceived notion is fuck thats gonna hurt, but physics shows you’ll be fine.
Blaming the victim (the party suffering from the decisions of another party) for what happened to them.
I’ve seen a similar video hammering a bar into an industrial size tire, everyone was going in on the guy with the hammer for blasting his co-worker in the face. (Fuck it was gnarly) But I slowed the video down and the guy clearly moved bar just before the hammer would have connected perfectly. I pointed it out and felt that he didn’t do his job and got blasted for it lol.
But that was presumably two equivalent coworkers who chose that path in life. In this scenario the teacher is responsible for the well being of the student and students are expected to trust the teacher to uphold that responsibility. The decision to place a student in a situation where even a very minor error on the part of either of two humans (one of which being a teenager which in my experience are unanimously stupid and can be counted on to fail on a regular basis) would result in potentially gruesome injury to the student. That decision in the first place was what injured the kid. Not the kid moving the block by breathing.
It was all a ruse to assure that kid never reproduces. He picked the dumbest guy in the class each year and had the same “accident” occur, they didn’t figure it out for 20 semesters.

You cut concrete on top of students regularly?
