ABSTRACT:
A one-piece flattened tubular member is formed into the shape of a U. The formed bottom of the U can be mounted over an automobile glass window and then the window is closed so as to retain the device mounted on an automobile. The ends of the flattened tubular member are slanted or tapered transversely to the width of the tubular member so that when the device is mounted in one direction on an automobile window, forward motion of the automobile will effect a vacuum along the outer edge of the tubular member and thus suck air from inside the automobile. When the device is mounted in the opposite direction on an automobile window, pressure created by movement of the vehicle along the outer edge of the tubular member creates air pressure within the automobile.
