How it worksHow it works

Exfoliated clay is added to a liquid polymer that Exfoliated clay is added to a liquid polymer that lines the inside of the balllines the inside of the ball

The clay plates overlap each other in a parallel The clay plates overlap each other in a parallel mannermanner

Since the plates over lap each other the air Since the plates over lap each other the air must travel through many layers to escape the must travel through many layers to escape the inside bladderinside bladder

Therefore the air stays inside the ball betterTherefore the air stays inside the ball better
