I've already found that drinking cola, great big gulps of it, gives me the loudest burps. But my first glas is a bit disappointing - the cola has gone flat and I get funny little frothy burps instead. I shot a second video to show off exactly how much I can burp with a glass from a just opened bottle - you can see the bubbles jumping over the edge of the glass and compare my burps!
