Answer:
Since cold air settles and warm air rises, the tape is 'carried' up by the warm updraft. That's why you can enjoy the cold breeze of the fan. That's why the calendar pages are flipping back ;)

Answer:
Explanation:as velocity increases pressure decreases when we switch on a fan the velocity on front side of calendar paper will be more so pressure decreses as the pressure on backside of paper is more it exerts force from backside so papers move front.The same happens for flying of airplane(dynamic lift) based on Bernoulli's principle
