Note: The device is not restricted to be used as a stress ball only. You may also use it for amusement, to throw at things (such as burglars), as a christmas/birthday present, for practical jokes, as a keychain, to pretend it's fruit, to sell, to launch into space, to juggle or any other use you can think of.
Step 1: What you'll need
You will need the following:
Step 2: Stretch the balloon
Step 3: Fill it with flour
Step 4: Avoid a disaster
Step 5: Enjoy
You may now fully enjoy your fabulous flour stress ball in any way you could possibly imagine.
If you do not have an imagination, you will unfortunately be forced to use it solely as a stress ball.
