Slicing the Ball
A sharp blade makes the cutting a bit easier. Cut a slice approximately 1-inch long, and then cut another slit perpendicular to the first to create an X-shaped slice. Push the ball onto the bottom of a chair leg through the X-cut to finish the chair slider.

Simply so, why do people put tennis balls on walkers?
People put tennis balls on walkers to make them quieter, to protect floors, and to make it easier to push the walker along. There are tennis balls made specifically for walkers. You can cut a tennis ball for a walker using a serrated knife or by putting it in a vice and using a saw, but be careful!
