Here is a simple, new way to play balloon volleyball.  Just blow up a bunch of balloons and put them in a clear, plastic bag.  Starting tossing the giant bag of balloons.  The balloon bag allows for a large, very slow moving target to help children who may be just learning how to catch.
Try playing a game of balloon volleyball.  Try laying on your back and hitting the giant balloon bag with your feet to add in some core strengthening.  See what games your child can create with the big bag of balloons.
