I've never had the courage to try to swallow cola and mentos at the same time... until now! I am very curious to see what reaction my tummy will have. ... Oh dear, my belly is starting to swell... the muffin top is sticking out and the shorts I'm wearing are getting tighter and tighter, I'm sure once they are unbuttoned it will be impossible to close them again.  Unlike the videos I have seen online, no mammoth burp releases me from this internal pressure... rather, my belly continues to swell from all the trapped gas.  ​​​​​​​I feel the gas caught in my belly expanding more and more, taking up all the available space. My belly is a giant balloon now. I burp slightly but it is not enough, the gas remains trapped inside me.  "I have to be careful not to go near any needles in this condition..."
