Juggling was never a very easy activity to learn.  In fact only a few times have I managed to throw the balls in the air and catch them 5 or 6 times, and I'm pretty darn confident that a considerable amount of luck was involved in these cases!  However, in my experience children actually DO like to learn to juggle.  It's one of those activities that's fun for a little while but requires so much patience and determination to actually master that most people give up (such as myself).  Still, juggling is fun for a little while and besides, these balls can be used to throw across the room/yard and even play a game of catch with your dog so it's not all bad!  At least they're very cheap to buy.
