The video is being made. Until it arrives, here is what it will say (119 words, about 60 seconds):

Here's a ball on the grass. It sits still. Nobody touches it, and it doesn't move.

Now the boy runs up and kicks it. Off it goes!

It rolls straight toward a girl. She stops it with her foot.

Then she taps it to the side, and it rolls off a new way.

It took a kick to start the ball moving. But what did it take to stop it? And to turn it?

Did those need a push too?
