Here is a short tutorial about how to make your own balloon ball toys.
First you have to get that balloon in your mouth.
OK you have to try to find the sticky outy part that has an open end. Hold the balloon by that part and get the rest of it hanging outside your mouth.
Now blow, like when you go up to your moms face real close and breath demon doggy breath on her. The goal is the trap all the doggy breath inside the balloon.
Keep blowing, and blowing, and blowing.
I recommend for first timers to ask your thumbed companions to do this for you. It takes lots of practice. My method, you can see here, involves holding it down with one paw and wrapping the sticky outy around a long tooth, then I use my tongue here to tuck the end back over and Tada!
Enjoy until explosion!
