What you will need;
One Cup of Flour
Cheese Cloth or
Dish Towl
Running Water
Put the flour in the middle of the cheese cloth or dish towl and
draw up the ends of the towl. Hold this under running water, while
squeezing the flour into a ball so that all the starch rinses out.
Continue this until the flour becomes a sticky, gray mass.
You should be left with a ball about a half inch in diameter.
Place this in your mouth and chew, swallowing any remaining
starch as you chew. You're now ready to blow.
With a bit of practice, this makes bigger bubbles than the store
bubble gums. You just have to learn to get used to the taste.
