What is the pok-a-tok ball made out of?

the Pok-ol-pok ball is made out of rubber found and made from the bark of a tree 3000 years ago. you play by hitting the ball with your hip, by wearing a bronze belt.

actually that is a lie i just did a report on Maya and you play a game where the is a 8 pound ball and there are these metal plates on the wall and if you hit one you get one point and you cant use your hands and there also is a hoop and the game is so hard that they made whoever got the ball through the hoop wins and the loser coach gets their head cut off by the winning coach
