That means that whatever shape a bubble has when it is first formed, it will try to become a sphere. Bubbles will form 120 degree angles where they meet. You may start to notice that when you get a ton of bubbles going that they start to form hexagons. When bubbles of different sizes meet, one will become a bulge onto the larger bubble. Each soap molecule is oriented so that its polar (hydrophilic) head faces the water, while its hydrophobic hydrocarbon tail extends away from the water layer. A thin layer of water is sandwiched between two layers of soap molecules. The film that makes the bubble has three layers. However, when two bubbles of similar size meet, they merge together creating the least possible surface area. ![]() You can liken a bubble to a balloon in that a balloon has a thin skin of rubber filled with air. What’s the science behind bubbles? Bubbles are made up of a thin wall of soapy film that fills with air. Our science activities and experiments are designed with you, the parent or teacher, in mind!
