A few weeks ago, Guinness World Records’ Editor-in-Chief Craig Glenday attended The Big Bang Fair in Birmingham, UK – and brought a special guest along with him.

Craig challenged the kids at the science exhibition to work out what record title Paul Hunn holds.

See if you can work it out before them and check out the kids’ hilarious shocked reactions in the video below.

Once they found out that Paul can do the world’s Loudest burp, a few kids decided to see how their belches measure up against his exceptional 109.9-decibel achievement.

Though there were some impressive attempts, Paul proved that he remains unmatched in his burping prowess.
