The #BritainBreathing team had a great day out at the Manchester Science Festival in October 2015, talking all things allergy-related. With the help of our giant nose and a range of interactive and fun hands-on science experiments, we asked the good people of Manchester, “What makes you sneeze?” The day was also a great opportunity for us to trial a prototype of the #BritainBreathing app and gauge support for the project with our interactive polling station.
