The science of soap foam and bubbles

When Sa Bu and water come together, the foam turns. Foam is a microscopic bubble. No matter what color the soap is, its foam always turns white. The bubbles are transparent. The transparent thing does not have color. Bubbles that are blown into the air with soap bubbles are a popular children's game. Water thin

It's fun to watch bubbles flying in the surface air. The bubble wall, though quite thin, is made up of three layers. There is a layer of water between the two walls of the soap molecules. Soap molecules or molecules have the property that their head is always towards the water. So all the molecules form a lined wall.

It is rounded to keep the wall area to a minimum. When two bubbles flying in the air collide with each other, they get stuck at a 180 degree angle. And both float in the air together. Bubbles break when molecules evaporate from atmospheric heat.

A little glycerin is added to the soapy water to keep the bubbles floating in the air for a long time. Glycerin slows down the evaporation of water. At the fair, many hawkers are seen selling bubble blowing liquid. It also contains some other chemicals.
