(11 in.) on the set of Guinness World Records: Primetime, Los Angeles, USA on 10 November 2000.  Joyce, who has been chewing gum since she was 12 years old, began putting the gum on her nose to blow bubbles for entertaining her children.

She pre-chews the gum for at least an hour to get the sugar out, before making it into a rectangle shape with her hands and putting it over her nostrils.
