But if a many bubbles meet, the cells will form hexagons. Bubbles meet to form walls at an angle of 120 degrees. When bubbles that are different sizes meet, the smaller bubble will bulge into the large bubble.

When same size bubbles meet, the wall that separates them will be flat. Why? Because this shape requires the least energy to achieve. But when bubbles stack, they will merge walls to minimize their surface area. (Thank you for that very technical definition.) Shapes Bubbles LikeĪ bubble will attempt to become a sphere. 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. Bubbles Actually Have Three Layers:Ī very thin layer of water is sandwiched between two layers of soap molecules. The bubbles children play with are usually just filled with air, but bubbles can technically be filled with any gas. What Is a Bubble?Ī bubble is simply a pocket of air wrapped in a thin film of soap. So go ahead and make your own unpoppable bubbles and beat the evaporation odds with this DIY science experiment.
