2.The lather of a shampoo has nothing to do with its ability to cleanse
You might think that the more foam a shampoo, the better the cleansing power. But in reality, the foam of a shampoo is not directly related to its cleansing power.
The cause of foaming in shampoos is the surfactants, which reduce the surface tension of the water and allow the shampoo to mix better with the oils and dirt on the scalp.

Bees mainly collect nectar for water and energy. In the process of collecting nectar, they use their tongues to suck the nectar and store the nectar on the honey navel in the honeycomb.
Bees try to absorb as much water as possible from the nectar when collecting it and then return to the nest to evaporate the water to make a viscous honey.
This is one of the reasons why honey made by bees can be preserved for a long time because the moisture content in honey is very low.
4.The flame is invisible
The flames we usually see are colored, but in reality, the flames themselves are colorless and formless.
The color of the flame comes from the different elements in the burning substance, and when these elements are excited, they emit a specific wavelength of light, thus manifesting themselves as different colors. For example, when wood is burned, the flame takes on a yellow to orange color.
At the same time, what we call a flame is not completely invisible, because the flame we usually see is actually visible light produced by the chemical reaction between the surrounding gas and the combustible. If the substance is ignited in a vacuum, there will be no visible flame even if there is combustion.

Each silk is made of thousands or even tens of thousands of silk protein helixes tightly wound, which makes silk tough, soft and breathable, making it an ideal raw material for making high-end textiles.
