crumple a small piece of paper into a ball size smaller than the mouth of the empty bottle.hold the empty bottle on its side and place the paper ball just inside its try to blow on the ball to force it into the bottle.try the activity with battles of different sizes.

when we blow into the mouth of the bottle,the air near the mouth has higher speed. this decreases the pressure there . the air pressure inside the bottle is higher than near the mouth.
