Space Spirit Spring: Farmer Girl Cleverly Headed Home

Su Haitang motioned to her to rotate the card by an angle.

"Have you seen? There is a very beautiful light here. What color do you think it is?"

"Lavender?"

Xuanyuanmin squinted uncertainly.

"Let's show it to my uncle." Su Haitang sold Guanzi with a smile.

"Can you still see the flowers? I'm not color blind."

Xuanyuanmin complained a little, and handed the card to her husband graciously.

Su Junyue turned the card indifferently, and Dan Feng's elegant eyes opened wider and wider!

"What's going on? I look bright yellow!"

"Impossible!" Xuanyuanmin leaned forward in disbelief, and the two heads to each other to watch together!

"It's lavender, it's a bit pink." Xuanyuanmin emphasized.

"Bright yellow, it's obvious." Su Junyue emphasized firmly.

"What's the matter?"

The couple glanced at each other and asked about Su Haitang, who the old **** was smiling.

"It's just a little blindfold." Su Haitang smiled lightly to decrypt.

"Let's talk while eating." Su Haitang greeted actively.

"To put it bluntly, it's not worth anything. The light is roughly due to the combination of the seven-color spectrum, but it merges into transparency."

"For example, diamond cutting, creating some angles, can reflect the bright light, which is captured by our retina, forming a vivid color perception."

"The human retina, like fingerprints, is also very different. With the habit of using the eyes, there are more or less problems, such as myopia astigmatism, the speed of the optic nerve response, and so on."

"It's probably the principle anyway, some special patterns will show subtle differences in the eyes of different people. And I made this difference infinitely widened by mistake."

In fact, she did an experiment on a whim. She took out a little cold spring water, plus five kinds of leaves of the five-color tree, and also took a little dust particles from the space stars, and then the heat and cold acted violently, and a little dust powder after the explosion was mixed into the card material. , It's just a magical phenomenon.

It happened to be used by her for anti-counterfeiting.

It's just that this unexplained coincidence can only be done once. Otherwise, what should she do if she is asked to design coin anti-counterfeiting? Where can she come up with a rigorous and reasonable scientific explanation?

"Is it so magical?" Xuanyuan Min flipped through the cards enthusiastically, all of which looked like lavender.

Su Junyue looked at Su Haitang with deep eyes, frowning slightly.

"Is there any more card? Give me one. I call those old men from the Department of Physical Chemistry and Optics to study it."

Su Haitang was not afraid of revealing the stuffing at all, so he trot and took out another one and offered it with both hands.

"Let me see."

Xuanyuanmin leaned over, and the couple looked for a suitable angle as if turning a thermometer.

"blue purple."

"Dark gold."

The couple looked at each other and both looked serious.

"You may have other uses for this thing. When the VIP card is issued, it is too big and underwhelming. Take out as much as possible."

"Write a detailed report on your formula and production process, and I will hand it in. Don't worry, you won't be taken for nothing."

Xuanyuanmin spoke seriously.

Su Haitang was actually ready for this.

It’s just that, it’s too tricky. She didn't decide whether to report it.

It’s not easy to take credit if you don’t know the principle, and you can’t replicate it successfully.

Unless she reports the secret of the space.

But in this way, she will definitely become a national treasure-level key protection object, and her freedom will be restricted, just like Su Haiyan.

She didn't want to take this risk, it was completely unnecessary.

"Do you also find this useful?"

Su Haitang explained with a smile.

"I thought I had inadvertently made an amazing super invention, and I wanted to take credit for it. Unfortunately, I wanted to break my mind and try hundreds of times, but I still didn't succeed."

"This is really an accident."
