Pick a drink that is cold but not so cold that it hurts to drink quickly. Avoid drinks that have gone flat and have been open for a long time.
You don’t need to take large mouthfuls, smaller sips will introduce more air as you swallow. Resist the urge to let out small burps as you drink.
Open your mouth. Squeeze your stomach muscles similar to the feeling of vomiting. Let the air escape your stomach.
Pull the air in your mouth to the back of your throat. Swallow a gulp of air.
Prepare for the upcoming burp by pushing all the air into one bubble. Hold the burp in for a moment to build up pressure.
A longer burp will generate louder sounds. Contract your diaphragm muscles towards the end of your burp to squeeze any remaining air out. Keep your mouth open during the burp so the sound is not muffled.
