burps

[tartwitahart]

why is it that whenever you have pop or fizzy drinks it makes you burp??

[brachiopod]

This is basic science - the sort you learn in school and you find 'soo-oo-oo boring'. (qv your question in 'science')

"Fizzy drinks" are water with a gas called carbon dioxide (CO2) dissolved in it. The gas is kept in solution by the bottle top or closed can. Once opened the gas starts to exsolve or come out of solution ('fizz') - eventually going 'flat'.

When you drink your sugar-laden concoction, the carbon dioxide comes out of solution in your stomach, increasing the gas pressure within it. The increased gas pressure tries to 'force itself out', making you burp.

Apart from fizzy drinks your stomach makes its own co2. If you wernt able to get rid of this heavy gas your stomach would literally explode!
