You can’t bounce a ball under a table

This is video illustrates something my siblings and I tested out with a bouncy ball and our dining room table back in the day until the ball got lodged inside a radiator cover. It’s probably an experiment most kids have tested without knowing at some point or another! A commenter pointed out that playing racquetball for the first time is a nearly perfect real life example the section of the video that illustrates the ball’s movement from within a cube. The slow motion really does help illustrate the physics behind it. From Steve Mould on YouTube:

If you try to pass a bouncy ball under a table, if it hits the underside of the table it will just bounce back out the way it came.
