During ERS 2007 in Stockholm we offered doctors who visited our stand, a chance to win a spirometer by participating in quiz. The task was to try to estimate how many flow transducers were placed in a transparent tube. The quiz was so popular that we decided to conduct this quiz in Berlin as well. The tube was of different size than last year to give everyone equal chance to win.

The correct answer was 829.

We have a pleasure to announce that this year there are 5 winners:

5th of October won:
• Mr Adam N. from Poland with his guess 823

• Mr. Miguel R. R. From Spain with his quess 823
• Mr Reinhardt E. From Germany with his guess 823

7th of October won:
