I was challenged by a fan to see just how big my burps can get after taking time off! I used the gulping method to try to build my burps up to be as big as possible. There are fewer burps in the first half where I stayed true to the "gulping method" by gulping in as much air as possible and letting it erupt out of me, and then later on I began really pushing the burps out. There are plenty of 10+ second burps and I think the longest was 13 seconds!
