OK you were warned. I ride the train to work every day.
Recently I was urinating. (For those who don't know me
I'm a male-type person.) The train braked and the stream
began following a curved path. For a second I thought,
"Oh Geez, did my you-know-what just break?" And then I
realized, (in unison now) "No dummy, it's a non-inertial
reference frame!"
See, it was physics, after all. No, I'm not doing this
demo for my class.
