Most of you enjoy the view from a glass but when privacy is needed you would need to get up and draws the blinds. But did you know that there are glasses which can turn from transparent to opaque by a flip of a switch? These are known as electrified switchable glass. This glass has 2 thin films inside the glass. Between these 2 thin films there is a liquid crystal layer. In this liquid crystal layer there are liquid crystal molecules. When electricity is not applied these liquid crystal molecules will be randomly oriented and will scatter light. This makes the glass opaque. But when electricity is applied these liquid crystal molecules will line up, allowing light to pass through, making the glass transparent.
