There were knockerballs all over Claudia Driscoll Park in Hamilton Saturday.

The new, fun activity was sponsored by the Ravalli County Museum and introduced people to the big, wearable plastic balls.

The events were split into three categories:
Freestyle - where you put on the knockerball and walked, rolled or jumped around.
Tournament - You and your friends try to move a soccer ball down the course, bumping into each other as you go.
Slip-n-slide - a slippery detergent is applied to the outside of the ball and you run and slide on a plastic cover.

Knockerball Grand Rapids provided the balls and music. There were also booths offering food and drink at the Hamilton park Saturday.
