If you play tennis, even if you play horribly and only a few times a year (like we do), then you probably have a tube of old tennis balls in the trunk of your car. Test 'em out. They probably don't have much bounce left in them, which means it's time to try one of these ten ideas
...We had no idea how useful old tennis balls could be until we read this article over atThis Old House
Here are our favorite three:
1. Protect a padlock: "Cut a slit in a tennis ball with a utility knife and slip it over an outdoor padlock to prevent water from getting into it and freezing."
2.Open a jar: "Cut a tennis ball in half. Use the open end to grip and unscrew tight lids."
3. Collect change for tolls: "Cut a slit in a tennis ball and stash spare change inside. Keep the ball in your car so you don’t have to grope for your wallet when you’re at the tollbooth."
Get the rest here.
