How to tie a balloon knot, you must have it.

First, we have to inflate the selected balloon, then we have to hold the 1cm behind the mouthpiece with the thumb, forefinger and middle finger of the left hand at the same time, and then stretch the 1cm part reserved for the atmosphere with the right hand. The right hand passes through the backhand opening between the left hand and the balloon, the right hand holds the top of the balloon, and the right hand directly holds the mouthpiece. Finally, pull the two-finger balloon out of the transnational air outlet with your right hand. It sounds complicated, but in fact, the real teacher's teaching seems much simpler.

One-handed knot:

1. Hold the balloon in your left hand, hold the mouthpiece with your thumb and forefinger in your right hand at the same time, then lengthen the mouthpiece with your right hand, preferably a little longer, and hold the mouth with your thumb in your right hand.

2. Turn the right hand slightly by 180 degrees, so that the elongated balloon is wrapped around the index finger of the right hand.

3. The thumb and forefinger press each other hard, and at the same time let the mouthpiece roll in opposite directions between the two fingers. When the index finger leaves the entangled balloon, the mouthpiece will naturally be hooked into the knot by the index finger, and the knot will be finished.
