You will need:
*Rice/ something really cheap.
*Thin plastic bags similar to those that you find in the supermarket.
Put some of the rice into one of the bags. I worked out how much I needed by eye and all three of the juggle bags are slightly uneven in size, they look about the size of a ping pong ball.
Trim off the excess section of the bag.
Trim off the top of the balloon so that you are left with the bottom section.
You will then need to stretch the balloon over the bag of rice, carefully so as not too split it. You will be left with a space and the rice can be seen.
Put a second balloon over the gap on the top of the juggle ball.
With a third balloon carefully cut some holes into it. Make sure not to over do this, or you will end up ripping it as you try to put it over the juggle bag.
This will enable the colour below to show through and make the juggle bag stronger.
