Use two mirror strips about 15 cm long and 3 cm wide (you can go to the glass shop to buy scraps).
Cut another piece of cardboard the same size as the mirror strip and blacken one side of it. Combine two mirror strips and a piece of cardboard as shown in the picture (the black side of the cardboard should face inward), stick them with adhesive tape, and then tie them tightly with two rubber bands.
This becomes the simplest kaleidoscope. Put some colored scraps of paper and colored glass beads on a piece of white paper.
Look at them through the kaleidoscope, and you will see many star-shaped patterns. Rotate the kaleidoscope and the pattern will change accordingly.
If you don't have mirror strips, you can use glass strips instead, but you should paint one side of the glass black or stick black paper on it, and the black side should face outwards. However, the kaleidoscope made of mirror bars looks much brighter than that made of glass bars.

Small production-kaleidoscope composition
Small production-kaleidoscope In science class, Teacher Zhou explained the principle of light to us, let's make a kaleidoscope and tell us the materials for making kaleidoscope.
When I got home at noon, I couldn't wait to tell my father the idea of making a kaleidoscope. Dad smiled and said, "What materials should we prepare to make a kaleidoscope?" "Very simple."
I handed my father the list of materials for making kaleidoscope and said confidently, "As long as I have these materials, I promise I can make kaleidoscope." In the evening, dad got a lot of materials from nowhere and put them on the table.
I saw a round and long paper tube, three rectangular lenses, placed in front like a "general", followed by double-sided adhesive tape, transparent film, transparent adhesive tape, cow paper, round paper with holes in the middle, collar, and a dozen colorful beads. They are like troops waiting for me to go to war.
When the materials are ready, just do it. First of all, I stuck thin and long double-sided tape on the back of three lenses, and took off the protective film of the double-sided tape. After doing this, I stuck the mirror on kraft paper.
Remember, leave a little gap when sticking. Then remove the original protective film of the lens. In the process of removing the film, don't touch the mirror with your hands, otherwise, the kaleidoscope will not be good enough.
Then surround the lens into a triangle, stick the lens with transparent adhesive tape, remember to stick it firmly and put it into a long paper tube. Finally, put a transparent film on one side of the long paper tube, and then put the small round paper with holes and a collar; At the other end of the cylinder, a transparent film and a smaller collar are installed, and the small colored beads are filled, and the small colored beads are sealed in the cylinder with the transparent film and the collar.
A simple kaleidoscope is ready. In order to make it look better, I drew colorful patterns on the long paper tube with colored pens.
I put the kaleidoscope in front of my eyes and looked around. I saw some beautiful patterns; Some are like colorful flowers, some are like green bamboo forests, and some are like bright red sun ... The next day, I handed the kaleidoscope to Teacher Zhou.
Teacher Zhou praised me for my good work, and I was filled with joy. This kaleidoscope production has improved my practical ability and enriched my after-school life.
Experience of kaleidoscope making
Kaleidoscope is an optical toy. As long as you look into the tube, a beautiful "flower" will appear. Turn it slightly, and another flower pattern will appear. The pattern is constantly changing, so it is called "kaleidoscope". How did the kaleidoscope pattern come from? Originally, it was reflected by the glass off the mirror. It consists of three glass mirrors to form a prism, and then some glass fragments of various colors are placed at one end. After these fragments are reflected by the three glass mirrors, a symmetrical pattern will appear, which looks like a blooming flower. The principle of kaleidoscope lies in the reflection of light, and the mirror uses the reflection of light to image. This imaging principle has been mastered by the ancients in ancient China. In the ancient book Zhuangzi, there is a saying that "learning from water stops", that is, still water is used as a mirror. It is said that the real kaleidoscope toy was invented by the British physicist David Bursa in 18 16, and the Chinese people also had this kind of toy very early, and it was innovative. Many new kaleidoSCOPEs have been produced. The structure and mystery of kaleidoscope lies in its exquisitely designed mirror structure and flowing patterns. Just like the English name of kaleidoscope, * * * the Greek beautiful words such as KALOS "beauty", EIDOS "shape" and scope "look" are added to summarize its main features. "Beauty", Of course, it refers to the ever-changing scenery in the kaleidoscope, and it is also the "core" of the kaleidoscope (the subject matter for viewing), which is also the place where the kaleidoscope-making artists make the greatest efforts. Moreover, in the creative process, the selection stage of the "core" is the time when the fun of making kaleidoscope can be best realized. The material of the "core" is very extensive, such as colored glass, precious stones, bird feathers, dried flowers, etc. All of them can be used as beautiful patterns of kaleidoscope. According to experts who make kaleidoscope, there are many types of "core". For example, combining two windmill-shaped wheels together to form various patterns by rotating the wheels, or installing glass balls at the front end and rotating it to watch any scenery around you, you can get an unprecedented fresh composition. And the front end is filled with a combination of various colors of oil. And through the flow of oil to produce incredible patterns. "Shape" mainly refers to the mirror structure of kaleidoscope, including two mirrors, three mirrors, four mirrors, cone, rotation and other structures, so that we can see the scene, not only the sweetness of the circle, the evolution of polygons, but also the charm of fireworks. China's kaleidoscope entered China about 100 years ago. Due to the production at that time, Kaleidoscope can only be treasured as the private rooms of the dignitaries of the Qing Dynasty. With the breaking of the closed door policy of the feudal dynasty and the development of China's national industry, the cost of kaleidoscope has gradually become low. In the old days, Wang Xie Tang and Qian Yan also flew into the homes of ordinary people. Back decades ago, kaleidoscope was already a common and easy-to-get toy in the stalls in Beijing Hutong. How many children's simple and happy childhoods have been sketched out. In children's eyes, the "flowers" in kaleidoscope are just like butterfly incarnated by Liang Zhu, peony in Wu Zetian's eyes, and a fairy with a hundred flowers. A kind of "flowers" has gone away, and it is difficult to reappear for decades. In the earlier kaleidoscope, the flowers were cut into pieces of colored paper with poor transparency. Later, some people tried to use more transparent colored broken glass. It has become colored plastic sheets and smooth glass beads, and the three pieces of glass used for reflection have also been replaced by three mirrors. As time goes by, the materials used to make kaleidoscopes have changed, but the only constant is the enthusiasm of children for the magical world in kaleidoscopes. People like to see kaleidoscopes and prefer to make kaleidoscopes by hand. At the Dongyue Temple Folk Games in Beijing, it was about 90 cm long and its diameter was 10. Kaleidoscope made by amateurs using waste paper tubes. At present, Beijing Folk Museum also has a collection of kaleidoscope made by Mr. Li Hongkuan, executive director of Beijing Toy Association, with a length of 132 cm. A large kaleidoscope with a diameter of 25 cm. The kaleidoscope is simply made by using two mirror strips with a length of about 15 cm and a width of 3 cm (you can go to a glass shop to buy scraps). Then cut a piece of cardboard with the same size as the mirror strips and paint one side of it black. Combine the two mirror strips with a piece of cardboard as shown in the picture (the black side of the cardboard should face inward) and stick them with adhesive tape. Tie them tightly with two rubber bands. This becomes the simplest kaleidoscope. Put some colored scraps of paper and colored glass beads on a piece of white paper. Observe them through the kaleidoscope, and you will see many star-shaped patterns. Rotate the kaleidoscope, and the patterns will change accordingly. If you don't have mirror strips, you can use glass strips instead, but you should paint one side of the glass black or stick black paper on it, and the black side should face outwards.
Simple method of how to make kaleidoscope
1, a paper roller, the core of plastic wrap is very good. Choose a one with a diameter of 3-4 cm and a length of about 20 cm, and cut it if it is too long.
2. When you go to the glass shop, ask the shop assistant to help you cut out three glass mirror strips, which are19.5cm long and 2.7cm wide. 3. Two glass discs with a diameter of about 3 cm, slightly smaller than the diameter of the paper tube.
The one on the right is frosted glass, and the other is transparent white glass. The transparent white glass sealing the observation end also needs to cut a piece of colored circle paper, which is used to leave an observation hole of appropriate size and cover the excess part.
4, there are a little colored scraps of paper, and the yellow scraps are broken table tennis. 5, glue, transparent tape.
6, a small piece of wrapping paper. Manufacturing process: Tie three mirror strips into a triangle with transparent adhesive tape, and the mirror faces inward to form Mitsubishi mirror.
Push the Mitsubishi lens into the plastic wrap tube, and leave 2-3 mm at both ends for the next step of sealing the lens. Then insert the frosted glass into one end of the paper tube and fix it with glue and transparent glue.
Put a little bit of colored paper scraps into the lens barrel, and then insert another transparent glass disc into the other end of the paper barrel, and seal it with glue and transparent glue. Finally, the surface of the paper roller is wrapped with beautiful wrapping paper, and the magical kaleidoscope is made.
It's very nice to put the kaleidoscope in front of the lamp at night, and the effect will be better when the light is good during the day! .
How to make a kaleidoscope with reflective paper
Just replace the mirrors mentioned below with reflective paper 1. First, prepare three small mirrors with the same size, and the ratio of length to width can be 5/2. If there is no mirror, just find some reflective materials ... 2. Arrange the three mirrors in an equilateral triangle, stick them together and fix them. 3. Cut some colorful scraps of paper. 4. Make a small box with transparent materials. The height should be such that the shredded paper can be put in and the paper can move at will. 5. Put the shredded paper in the box. 6. Stick the box under the triangular mirror. In order to prevent light, you can find a black roll to wrap the mirror and the side of the box. You can see it. You can find the ever-changing composition inside by shaking it gently.
