Take You To Know How Bubble Water Is Formed?

Blowing bubbles and playing with bubbles are the favorites of "cross-age" babies. No matter how old children are, including adults, it is difficult to resist the colorful temptation under the sun. Today I will show you how bubble water is formed!

How are bubbles formed?

Bubbles are formed due to the surface tension of water. But if there is too much adhesion between water molecules, bubbles are not easy to form. Soap "breaks" the surface tension of the water, reducing it to 1/3 of what it would normally be, which is the optimum tension for blowing bubbles.

Water evaporates very quickly. When the water evaporates, the bubbles disappear as soon as the surface of the bubbles is broken. Therefore, some substances must be added to the bubble solution to prevent the water from evaporating. Glycerin, for example, has a hygroscopic effect, which slows down the rate of water evaporation.

Why is the color of bubble water blowing colorful?

That's because light refracts at both the top and bottom of the soap bubble's film, which can contain up to about 150 different layers.

The dazzling color combinations we see are caused by unbalanced film layers. The thickest thin film layers reflect red light, the thinnest reflect violet light, and the center reflects other colored light.
