We think of tennis balls as having two primary purposes--the first is in a game of tennis and the second as a dog's fetch toy. But tennis balls can be recycled in a number of ways as creative solutions for common problems. Following is a list of ways you can recycle tennis balls.
Fluff up down-filled comforters and clothing. Toss a couple of tennis balls into the dryer with down vests, jackets, pillows and comforters to break up clumps of down and restore loft to the items.
Make a curved sander when refinishing furniture. Wrap a tennis ball in sandpaper to create a sander that fits the hand comfortably.
Protect a chrome trailer hitch with a tennis ball. Cut the ball in half and slip it over the hitch to keep out dampness and prevent corrosion.
Float two or three tennis balls in the pool to absorb swimmers' body oils. Replace the balls every two weeks.
Create a "gym safe." Make a two-inch slit along the seam of a tennis ball and insert valuables in it while working out at the gym. Keep the ball in the gym bag with other sporting gear.
Hang a tennis ball from the ceiling in the garage so that it hits the car windshield when the car is in the exact parking position. This makes parking easy every time.
Prevent the kids' bicycle kickstands from sinking into the grass or mud. Make a slit in a tennis ball and put it over the end of the kickstand.
