If you think that you can’t be surprised by classical physics any more, you should definitely watch the video I’ve uploaded below.

Here goes the follow-up video but don’t watch it without trying to answer the question posed in the first one. I was pretty much amazed how much attention the relatively simple problem can draw.

These two videos nicely show that physics is the experimental science. It doesn’t matter how great is your theory or how well you think you understand the well established theory, you should always be able to experimentally check your predictions.
