A bubble is a globule of one substance in another, usually gas in a liquid. Due to the Marangoni effect, bubbles may remain intact when they reach the surface of the immersive substance. ==Common examples== Bubbles are seen in many places in everyday life, for example: * As spontaneous nucleation of supersaturated carbon dioxide in soft drinks * As water vapor in boiling water * As air mixed into agitated water, such as below a waterfall * As sea foam * As given off in chemical reactions, e.g., baking soda + vinegar * As a gas trapped in glass during its manufacture * An air bubble in a solution of fluorescein and water (or alcohol) is the essential part of a spirit level 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「liquid bubble」の詳細全文を読む スポンサード リンク
