From their mesmerizing colours to their delicate shape... Soap bubbles hold more science than meets the eye. Why do soap bubble show different colours? W hat is the role of surface tension in keeping the bubbles spherical? What is the role of gravity in colours shown by the bubbles? Explore the answers in this blog post. --- Soap bubbles are far more than mere playthings: they are hollow spheres of soapy water enclosing air. Each bubble is composed of three delicate layers: an inner soap layer, a middle water layer and an outer soap layer. The formation of these layers is a result of the unique properties of soap molecules, which possess both hydrophobic (water-repelling) and hydrophilic (water-attracting) ends. The thickness of a soap bubble is not uniform; gravity plays a pivotal role in creating a gradient of thickness. The bubble is thickest at the bottom and thinnest at the top. This phenomenon occurs as gravity pulls the water molecules downward, yet surface tension act...
