The difficulty comes when you ask the next question: What causes inertia? Why do particles “want” to move in a straight line?

As the article points out, the highest rise happens when the water is in sync with the bucket, so you can’t attribute the phenomenon to friction.

What causes magnetism?

These questions won’t really stress me until we run out of ideas for physics experiments. :-)
