A full orange balloon is horizontal at the far left side of the screen. Air is let out of the balloon, forcing the balloon to fly across the screen to the light as it shrinks in size. The movement pauses when the balloon is in the middle of the screen. A black arrow appears pointing to the left away from the balloon. This arrow is labeled “Pressurized air escapes in this direction.” A second black arrow appears pointing to the right away from the balloon. This arrow is labeled “The entire balloon moves in the direction opposite the escaping air.” The arrows and labels fade out, and the animation of the balloon moving across to the right and shrinking continues until the balloon is off-screen.
