Add your Eos 20 drops and shake the bottle until well blended. 2. Blow up the balloon a little bit, and put it over the neck of the bottle. Transfer the flour from the bottle into the balloon. 3. Tie a knot on the balloon, ( little bit of flour might come poofing out when you do this, that’s OK). 4. Draw on a face using a sharpie marker.. 5. And then your stress ball is finished!
