How to?
With your palm flat:
- bring the index finger to your nose
- the soft part to your lips
- tuck the thumb into your palm
- open your mouth as if to yawn (or bite an apple)
- fill your lungs with air
Notice the deep sound of that inhale. Bright sound indicates restricted airflow.

We want the inhale-exhale cycle to be seamless, like a pendulum.
