Take a beautiful, and very deep, brick room and fill it, wall-to-wall, with a thick layer of soft, colorful yarn and thread waste and what do you get? A most unusual, and thoroughly fun, bouncy space where running, jumping, flipping through the air, turning summersaults, and of course, digging for treasure, are simply irresistible--and not just for kids. My five-year-old son wanted to stay all day. So did my husband.

You may be surprised to find that this fun is not in a play space or a children's museum, but at MoMA PS1, the contemporary art museum in Long Island City. Read on to find out more about this and some other exhibits at MoMA PS1 that will make checking it out in the exhibit's last weekend worth the trip.
