Balloons one per child
1/2 cup flour per balloon
Attach one balloon to the funnel by stretching out the opening in balloon onto the bottom of the funnel. Pour about 1/2 a cup of flour into funnel.
Start kneading the balloon. Some flour will fall in. This is the hard part. Keep kneading the top of the balloon the skinny part. When the balloon seems full of flour, knead the skinny part and push flour into balloon.
When the balloon is full, pull off the funnel and tie it.
