why bottom of bottles have flat or some unusual shape???


Why there is flat bottom of bottles and unusual shape of soft drinks???








              Soft drinks are served chilled. When a liquid Is cooled, it's volume change and the bottle must not buckle because of this change in volume. The coroner or the bump Or the tip of bumb can slightly expands/ contract without backing which takes care of the change in volume of liquid.
                Bottled water is not carbonated so there is no need For a pointed bottom. A flat bottom use less plastic, and holds up better in drop testing.
