cutting out your diaphragm.
Sing the Star Spangled Banner, backwards, in Lithuanian, while riding a bicycle that doesn't have a seat.
Take a deep breath then take in many breaths until your lungs are full to capacity then hold it for as long as you can, then breath out, reply of it works for you, it always does for me
put your index fingers in your ears and hold your nose closed with your little fingers then swallow...works everytime for me
Block your ears with your fingers and drink water.
Get a teaspoon of sugar and suck on it. Honestly it works
Drinking water backwards: drink from the far rim of the glass - have to tip your head upside down a bit - like curl over lol
