Tear off a 12? piece of cling film and line it to the inside of the bowl with the edges spilling out over the edge of the bowl. Spoon in 3 or 4 tablespoons of rice into the lined bowl.
Pull up the edges of the cling film and create a small bag of rice, twisting the top so that the rice doesn’t spill out easily. Then cut off the neck of a balloon.
Cover the juggling ball with a balloon. Putting your fingers inside the neck of the balloon and stretch it over the twisted opening of the cling film bag.
Cut the neck off another balloon in a different colour, stretch it over the first balloon and the opening that exposed the rice.
You can continue the process by layering of the juggling ball with different colored balloons.
