Classic juggling techniques to put on a backyard show. You will need 3 round tennis balls, alternatively you can make the balls by putting a couple of handfuls of rice or flower into a balloon. Start with one ball and lob it back and forth between your right or left hand. Now add a second ball! As you lob from your right hand to your left, release the ball in your left hand and catch the incoming ball, and repeat. After some practice you can introduce a third and then 4th ball by following the same steps.
