The Glass Ball deals with how fragile the earth is.
A baseball is hit into outer space with enormous power .

It is a race between the ball's fall down to earth (the ball transforms itself into the planet), and a bird that
with incresingly panic picks feathers from its own breast to make a nest to save "the glass ball".
"The glass ball" falls softly into the nest and the bird wraps itself caringly around it.

The glass ball fades into a ball and the nest transforms into a baseball mitten. The crowd cheers.
Suddenly the ball turns into a soap bubble. It gets deadly quiet... and the bubble bursts...
