You can’t say ‘Mmmm’ for 7 seconds

This is really interesting:
You can’t say ‘Mmmmmmmmmmmm’ for 7 seconds while holding your nose.

The reason? You have to exhale air through your nose to make some sounds. When you block the airflow, you can’t make this sound anymore. Do you know any other sounds that requires airflow through nose?
