Zorb Ball is a new extreme sport. It is a transparent sphere with a diameter of 3 meters and an inner diameter of 1.8 meters. It is flexible and can be used for two people to play at the same time. People enter the sphere and tie their seatbelts with their hands and feet. It rotates 360 degrees in disorder with the gradient of the site, just like astronauts feel weightlessness and rotation in space. It is very exciting.
