NARRATOR: Hello there.
Would you like to know how you're able to jump
and run like that?
It's your bones and muscles.
Your bones support your whole body.
BONE: [GIGGLING]
NARRATOR: That's your funny bone.
Your muscles allow you to move your bones, so that you can do
all sorts of things, like walking.
And running.
Your knees and feet help you jump and help you land safely.
We use the bones and muscles in our hands to catch.
And to throw!
Great shot.
The calcium in milk keeps your bones strong and healthy.
Running and jumping keeps your muscles strong.
BONE: Did you say jump?
