The more pink the static electricity, the more stable the emotions? The correct way to open the "static electricity challenge" is here.

The more pink the static electricity, the more stable the emotions? This winter, static electricity has been unlocked with "new", and the color of static electricity generated when touching different people is also different? Blue, purple, pink, red... Why is the color of static electricity different?

 fact, static electricity itself has no color, it just produces light of different colors when discharging.

High school physics tells us that any substance is composed of atoms. generation of static electricity is due to the fact that when objects rub against each other, the electrons in the atoms "run away from home", causing a difference in electric on the surface of the object. When the static electricity accumulates to a certain extent, and then touches or approaches a conductive object, it will move quickly, through the air, and form an electric spark. At this time, the current will excite the molecules in the air, release energy, and this energy will spread the form of light.

The light emitted by static electricity is mostly blue (purple), mainly because the current excites the nitrogen and oxygen molecules in the air, and frequency of the photons they release corresponds to blue (purple) light.

Those pink, yellow, and red static electricity are often related to the high and low voltage of electricity, the humidity and temperature of the air, and different discharge contact objects. Usually, when the static electricity voltage is high, the color of static electricity tends to blue and purple; when the static electricity voltage is low, the color of static electricity tends to be pink and red; if in the case of high-energy discharge, may also see a white glow.

So, this is not the "spark of love", and it can't be used as a basis for testing intimacy!

Here are little tricks to keep you away from static electricity:

1. Before shaking hands with someone, touch the wall with the palm of your hand first to release the current;

. Before touching the door handle, hold the key or other metal to contact the conductor first, so that they can bear the tip discharge first, and you can "";

3. Before wearing a sweater or coat, you can spray a mixture of clear water and fabric softener on the clothes first, so that the positive charge in fabric softener can neutralize the negative charge on the clothes, which can also reduce the generation of static electricity.
