While trekking in the Himalayas (in the Khumbu region of Nepal) for a month, and then working at a Nepali/Tibetan boarding school in Kathmandu (instead of the first semester of grade 8), I saw all the kids playing with this funny little toy they call a "chungy". They use it either as a foot-bag or dodge-ball. After weeks of sitting in the dark, I finally uncovered the secret of the little foot-bag/dodge-ball and how to make them.
What you'll need:
-something sharp (its not super necessary but I used really thick bands)
-something straight and thin (a pen, a stick, your friend's finger...)
-16-51 rubber bands OR an old bike inner tube (both should be about 1 inch in diameter and half a centimeter thick)
-a minute or three
-a good friend to help out and play with you after your done
Step 1: Prep
If you are using rubber bands, you can skip this step, but it might be nice to read.
Start by cutting anywhere from 16-51 bands from your inner tube. Each band should be about half a centimeter (quarter of an inch) thick, and no less than 1 inch (2.5 centimeters) in diameter. When you find/cut these bands, stack them on something straight to keep all of them organized and in one place. I bought some pre-cut bands so i have no picture for cutting up an inner-tube. After you have all the bands just snap or cut one. (Mo the Lego guy is just there to give you a sense of scale)
