In the center of the front yard, two tall persimmon trees, like two open giant umbrellas, shrouded the pond around a leafy leaf, adding a bit of comfortable coolness to the hot summer day, from time to time there is a wind blowing, the rustle of green leaves, the swaying posture of reeds, and the fragrance of wild chrysanthemums in full bloom, will create this world more and more comfortable and beautiful.

Definitely a great place to cool off.

Huo Minglou sat on the stone bench, took things out of the canvas bag, there were snacks from the department store, and three books, and finally, he took out two cylindrical things and handed them to Ling Zhi and Ling Yuan respectively.

Neither of them knew each other, and they looked curiously in their hands.

Ling Yuan couldn't wait to ask, "Uncle Huo, what is this?" ”

Huo Ming said, "This is called a kaleidoscope, it is an optical toy, put the bright color of the object at this end of the cylinder, place a prism in the middle of the cylinder, and seal the other end with an open glass, and then look from this hole, you can observe a variety of good-looking images, well, you two try ......"

He patiently explained while teaching the two how to operate.

The brothers followed what he said with great interest, and sure enough, they saw a scene that made them feel more magical, and they were immediately surprised, and then turned carefully, so that the picture inside kept changing, provoking them to exclaim again and again, as if opening the door to a new world.

When Song Hongguo came over with the boiled milk tea, the two little guys were excitedly pestering Huo Minglou to talk about the principle of the kaleidoscope, "The principle lies in the reflection of light, and the mirror is used to reflect the light to form an image, as long as you look at the eye of the tube, a pattern will appear." Turn it a little and another pattern will appear. Constantly turning, the pattern is also constantly changing, so it is called kaleidoscope. ”

The brothers listened very seriously, and from time to time raised new questions, "How did the pattern come about?" ”

Huo Minglou slowly explained, "It is reflected by glass mirrors. It is composed of three glass mirrors to form a prism, and then put something at one end, these things will be reflected by the three glass mirrors, and the corresponding pattern will appear. ”

The two of them seemed to understand whether they understood or not, and sighed, "The person who invented this toy is really at stake......

Huo Minglou said with a smile, "In fact, this imaging principle has been mastered by the ancients, and there is a saying in "Zhuangzi" that "it stops at water", that is, still water is used as a mirror. However, the real kaleidoscope toy was invented by the Scottish physicist David Brewster, and the folk in China also had this kind of toy very early, and there were innovations, and many new kaleidoscopes were produced. ”

When the two of them heard this, they couldn't help but sigh, and Ling Zhi asked thoughtfully, "If the things placed in there are different, you can get different patterns, right?" ”

Huo Minglou nodded approvingly, "That's right, the choice of this "core" is the most enjoyable to make a kaleidoscope, the materials are very extensive, such as stained glass, colorful feathers of birds, all kinds of dried flowers, etc., anything that can be thought of can be used as a beautiful pattern of the kaleidoscope, you can find everything to try, do it yourself, far more intuitive and interesting than how many times I said......"

The brothers' eyes lit up as they listened, "Can we do that too?" ”

Huo Minglou's eyes were full of encouragement and affirmation when he looked at the two of them, "Of course, I brought some materials, you can also disassemble this finished product and study it yourself before you do it, if you don't understand, feel free to ask me." ”

Hearing this, the two of them were immediately eager to try, but they were afraid that it would be broken, and they were a little reluctant and hesitant for a while.

Huo Minglou took out other materials, pointed them out in the same way, and finally said, "Be bold and let it go, don't shoot and tear it down, don't be afraid of failure, you find the most important thing to have fun with, if you learn knowledge by the way, it is the icing on the cake, as for the rest, I will give you a cover." ”

After saying this, the brothers were completely down-to-earth and couldn't wait to get started, but neither of them went to dismantle the finished product, not because they were afraid of demolishing it, but because it was a gift from Huo Minglou, they wanted to keep it intact as a souvenir.

Huo Minglou watched the two of them do it, and didn't help, only occasionally mentioning it, "In addition to what I said just now, you can also put in tightly tied silk threads, horsehair, and all kinds of spiral, curved small things." In this way, when the kaleidoscope turns, it is like enjoying a wonderful dance performance, of course, the difficulty level is a little higher, and when you are familiar with it, you can challenge and study it. ”

"Uh-huh, uh-huh......"

The brothers were full of energy and were so busy answering the call that they didn't even bother to drink Song Hongguo when they brought milk tea, you know, they were very worried about this before.

Song Hongguo didn't urge or bother, and handed a cup to Huo Minglou.

There are pearl balls in the milk tea, and it is not easy to use reeds as a straw to smoke in the mouth, so Song Hongguo uses a ceramic cup to hold it, and there is a delicate long-handled spoon in it, like drinking coffee.

Huo Minglou took it, lowered his head and sniffed it lightly, and after taking a sip, he stirred it with a spoon, dug up some pearls and ate it.

Song Hongguo asked, "How does it taste?" ”

Huo Minglou did not hesitate to praise her, "The taste is even better than the last time, sweet but not greasy, fragrant but not strong, it is really smooth and refreshing to drink, the small balls inside are like the finishing touch, eating and springing teeth, very chewy, really amazing." ”

Song Hongguo laughed, "Don't drink too much if you like it, milk tea is very hungry, otherwise I made delicious food at noon, I'm afraid you won't be able to eat it, there are spicy crayfish and sauerkraut fish you like......"

Huo Minglou's eyes were soft and bright, and he looked at her with a smile and said, "Don't be afraid, wait for me to do more work, and then I will digest it." ”

"Don't cut wheat today......"

"Then do something else, don't you have any other work at home?"

Song Hongguo saw that he was serious, and it was not good to dampen his enthusiasm, men, when you are willing to take the initiative to help women share housework, you must not shirk, shirk a few times, not to mention the fun, and he will not be enthusiastic to reach out in the future, many men don't care about being uncles at home, most of them are so used to being women, don't be afraid that he will not do well and refuse, if you do it a few more times, you will have experience, a good man also needs to be cultivated and trained, she is willing to pay patience.

The most important thing is that the way the two get along should set such a tone from the beginning.

"Then you can help clean up the roofs on both sides of the bungalow, and see if the fence around it is strong, and the ground, the cracks are big, it is better to smooth them, and when the wheat is cut, it will be dried on it."

Huo Minglou immediately responded, "Okay! Then after drinking milk tea, he rolled up his sleeves and went to work.

Seeing this, Li He and Wang Hongqi were not idle, so they hurried up to help.

In the end, not only did the cracks and potholes on the flat roof be smoothed, but also the exterior walls of the main house were repaired, and even the tiles on the roof were carefully inspected.
