A 13-year-old boy is claiming the world record for blowing balloons with his nose. Using one nostril at a time, Andrew Dahl inflated 213 balloons within an hour Friday in the town’s public library. His feat has been submitted for review by Guinness World Records.

His father, Doug Dahl, measured the balloons to make sure each was at least 20 centimeters, about 8 inches, the minimum diameter, and his mother, Wendy Dahl, kept the tally.

At one point he asked, “Does this count as practicing my trumpet?” His mother replied, “Only if you can play that with your nose.”

It was his second try. In February he sent a videotape of himself inflating 184 balloons, only to learn that it didn’t count because he handed them to his father to tie. This time he tied them off himself.
