To Keep A Piece Of Paper Horizontal, You Should Blow Over, Not Under

1.	To Keep A Piece Of Paper Horizontal, You Should Blow Over, Not Under It. Why?
Answer» By blowing over it, the speed of flow of air INCREASES and HENCE PRESSURE of air on it decreases slightly whereas the pressure below it is atmosphere hence the PAPER stays horizontal. By blowing over it, the speed of flow of air increases and hence pressure of air on it decreases slightly whereas the pressure below it is atmosphere hence the paper stays horizontal.
