BURPING
Have you ever been sitting in the middle of the cafeteria, enjoying your lunch break when out comes a loud burp? It’s too late to cover your mouth and besides all your best friends that are sitting with you have already heard you. Where did that burp come from?
Burps or belches are simply the sound of gas leaving your body. When you scarf down food or even nibble on it, you also swallow air. You’d be amazed at how much air you are breathing down your throat. If you’re drinking fizzy drink with your meal, you’re also swallowing another gas – carbon dioxide which is full of bubbles. Those bubbles don’t just float in your body, they’ve got to go somewhere. Other gas escapes from the stomach, travels up the esophagus and comes out your mouth. It doesn’t usually leave slowly. Gas can quickly escape which is why we can’t always cover our mouth before it comes out. Burps have a little to do with farts. Farts are the sounds and smells of gas that get through the butt. Burps are the sounds and smells of gas coming out of your mouth. During the day you probably burp at least 10 – 15 times.
If you want to burp the alphabet or your fav song here’s the secret. The more air you swallow the longer and louder your burp is gonna be. So swallow some air and then burp out a tune.
Did you know that cows burp a lot? It was only a while ago when researchers started taking interest in this. Every year the cows in the US burp 50 million tons of the valuable gases into the atmosphere. If these gases could be caught and directed, the burps of ten average cows could keep a small house heated for a year. These are some powerful burps.
