Ah, volleyball—a classic pastime of beachgoers everywhere. The only downside to this summer game might be the spray of sand in your face as you dive to dig the ball. No such problem when you bring the net to your backyard. Set it up for weekend fun or a summer party to turn your yard into a pop-up tournament-ready court, then roll it up when not in use to put your outdoor space back to normal. Available on Amazon; $40.99 (poles not included).
