Product description
However, if the water molecules are excessively bonded together, bubbles are not easy to form. Soap "breaks" the surface tension of water. It reduces the surface tension to only 1/3 of that under normal conditions. After the bubble is formed, a large surface tension is required to make the bubble bigger.
It is an interference phenomenon of light. When light passes through the film of soap bubbles, the top and bottom of the film will reflect. The soap film can contain about 150 different layers at most. The messy color combination we see is caused by the unbalanced film layer. The thickest film layer reflects red light, the thinnest reflects purple light, and the middle reflects seven-color light.
