It’s easy and inexpensive to make your own juggling balls for practice or, in my case, a whole bunch for workshops.
For each set of three balls, you’ll need:
300 grams of rice, about 1/2 cup for each ball
9 (or more) 9″ latex balloons
3 lightweight plastic bags or plastic wrap
scissors
tape (optional)
Cut the necks off the balloons. Pour 1/2 cup (100 grams) of rice into each bag. Twist the bag shut, removing any extra air, and trim the twisted end into a tail a few centimeters long. Optionally, tape the twisted part to the bag to prevent spillage. Open the cut end of the balloon and stretch it around the bag. Repeat with the remaining balloons, alternating sides to cover the circular gaps.
Done! The balloons tend to rip and shred when dropped on rough surfaces, so carry a few spare balloons with you for repairs.
