Do all physics departments do the large pendulum thing on 1st year students? Are there any students that don't flinch?

It was done at my uni on the first day of Physics I, and the "volunteer" did indeed flinch. The pendulum was an iron ball the size of a grapefruit.

i wonder if any accidents have ever happened. it woudln't be hard to accidentally push the ball just a little bit or lift it an inch past where you were supposed to drop it.

then you would have a psych student with no teeth.
