What you need:
- 3 balloons (about 11")
- about 3/4 cup of small dried beans (we used back beans)
Once your balloon is full of beans, snip the ribbed part of the neck. Then snip the necks in the same way off the other two. Take your second balloon and stretch it over the first one, covering the first one's neck. Repeat with the third balloon, snipping more off it's neck as needed so that you can see the color of the second balloon underneath.
And you're done! We're also toying with the idea of trying to use sand instead of beans to fill these for a different texture. Enjoy!
