A bubble is a thin film of soapy water. Most of the bubbles that you see are filled with air, but you can make a bubble using other gasses, such as carbon dioxide. The film that makes the bubble has three layers. A thin layer of water is sandwiched between two layers of soap molecules.

The Science of Bubbles: All you need to make a bubble is soap, water, and air…sounds pretty simple right? But the way bubbles are formed is actually a bit more complicated than that. You see, a bubble is a layer of water that is being sandwiched together by two layers of soap.

A bubble is a thin film of soapy water filled with air. The soapy film is composed of three layers: one layer of water molecules sandwiched between two layers of soap molecules. Millions of these molecules will stick together to form the spherical shape of a bubble. Now you just need to make this ultrastrong bubble solution and start playing!

As we have already discussed, a bubble is made of water, soap, and air. What do all three of these things have in common? They are all see-through! So when you blow a bubble, light waves can enter it from all angles and reflect off both the outer and inner surfaces of the bubble.

What’s the science behind (or inside) a bubble? Bubbles provide the opportunity to study science concepts such as elasticity, surface tension, chemistry, light, and even geometry. Your students can engage in processes such as observation, experimentation, investigation, and discovery, simply by studying bubbles.
