I'm going to take a wild guess that most of you have a random tennis ball (or 5) floating around your house. Whether from attempting a new hobby or a leftover toy that Fido lost interest in, they're just taking up space. But, there are tons of uses for all those fluorescent green balls, and we want to hear how you use them.
