Warning: Do not attempt this method at home. Or in a public place. Or ever. It's not safe. Or legal.
Step 1: Prepare your balloon. Inflated or deflated, it's your call. Just make sure it's not too big. Or too small. Or too... too pinched?
Step 2: Position yourself. Feet shoulder-width apart. Knees slightly bent. Hands firmly grasping the balloon. Or do it the other way, we won't judge.
Step 3: Squeeze. Hard. Fast. And with a sense of purpose. Or maybe just a sense of relief?
Remember: Practice makes... Well, that's not a joke. It's more like "Practice makes you need new lungs." Don't say we didn't warn you.
