textbooks

I remember seeing a few examples like this in physics:

Demonstrating the law of conservation of momentum with a M1 Garand.

I wonder if lots of publishers are getting pressured to swap them out for different examples?  Wouldn’t want to scare anyone.  If a police officer or a soldier was holding the gun it might be a little more acceptable, but still unnecessarily scary.  Probably better to use a non threatening cannon instead. haha

Thoughts?
