Good grief...

The test subject is lucky he didn't get castrated.

Moral of the story: don't hire idiots to teach physics.

The teacher is the one on the floor with his eager assistant Igor in an inertia, energy transfer/conservation demonstration.
It was very effective, the small chip from the edge of the block slowed the axe very little and left most of the energy to be transferred into his nether regions on the first swing.

Quote from a student.
"The teacher walked funny for like a couple of days and then he was just fine."

An axe? Really?

Seriously, from a safety standpoint, there are *so* many things that could have gone wrong.

And, for many of them, that face shield would have been useless.
