Maybe you have a newborn in the house, or you've a small pet that freaks out when they hear loud noises. Or maybe you're simply scared of popping balloons. But if you have a balloon that needs deflating, there are many ways to do it without that loud popping.
Hold the balloon in your nondominate hand and tuck the balloon under the that arm. Pinch the knot of the balloon between two fingers of your nondominate hand.
Gently pull the knot away from the balloon. Softly pinch the balloon just under the knot.
With a pair of scissors in your dominant hand, cut the knot off the balloon.
Slowly relax the fingers you have pinching the balloon and let the air deflate.
