Now, please ask Teacher Gui to help us make a new water ball.

Astronaut Zhu Yangzhu: Attention students, the ball did not break when it touched my racket, nor did it touch the surface of the towel. Instead, it bounced off like a table tennis ball. Now Teacher Gui is ready, let's try and see if we can fight each other.
