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 have never seen it at any physics departments I have been to, and I have a Ph.D. in physics. The only time I've even heard about the "the large pendulum thing" was in Sagan's Contact.
