We call those little pom-pom balls "shmuzzies" at our house (anyone seen "The Upside Down Show"?). I taped a bag to one side of the table and gave the kids straws and shmuzzies. They had so much fun blowing them into the bag. So much fun....really....my son has been doing this for days now. He has tried it with all different size shmuzzies and even some leaves. He has learned exactly how much he needs to blow and how to line up the shmuzzy so it goes in the bag.
