Si hits the road

Today, we got to put Si in the ball.  If you don't remember, Si is my class pet hamster.  Really, he started hitting the classroom walls.  The kids were doing their work while Si got to roam around.  When we went to get him, I grabbed the ball from behind Mrs. Piercy's desk.  He almost went through the cloth of the table, I caught him at the last second to prevent him from going under the table.
