Frenzel Method (throat piston)
Before this movie I equalised using 'hold nose and blow' method. The Frenzel method seems to be much more efficient.
1. Pinch your nose.
2. Fill your mouth up with a little bit of air.
3. Close the epiglottis.
4. Move the soft palate to the neutral position.
5. Use the tongue as a piston and push air towards the back of your throat.
