Every time the kaleidoscope rotates, the images inside change accordingly. The image you see may be your first encounter, or it may be your last encounter. Make a kaleidoscope and imprint the beauty of the moment in your heart.
From left to right and from top to bottom, the materials are:
1. 1000P White Jade Card
2. Wrapping paper
3. Battery holder, small light bulb
4. 3 slides (don’t doubt it, they are the kind used in biological experiments)
5. "Transparent" beads (discretion)
6. Electrical tape (black)
7. Test tubes and rubber stoppers
8. Matte film
9. Transparencies
Production process:
1. Use electrical tape to stick the slides together (the distance between the slides is 0.2cm).
2. Arrange three slides to form an equilateral triangle, and fix the top corners with electrical tape.
3. Completely cover the surface of the trihedron composed of glass slides with electrical tape.
Reminder: If it is not completely covered with electrical tape, the situation in the left picture below will occur. The light is transmitted, but the reflected image cannot be seen clearly. Although it is covered with electrical tape (as shown on the right below), the black tape absorbs a lot of light, resulting in the inability to have as good a reflection effect as a real mirror (one side of the glass is silver-plated). However, if other colors of tape are used, it will easily show through. Light will interfere with imaging.
4. Cut the 1000P white jade card, and slightly cut the cut white jade card along the blue dotted line in the picture with a utility knife to facilitate bending later.
This picture is provided by teacher Pan Guanqi. This kaleidoscope uses three mirrors of an equilateral triangle (for example, in this production, the included angle is 60 degrees).
The patterns and beads on each angle are reflected multiple times to form five images, and the objects are added to form a hexagon. I have previously made an isosceles triangular mirror with a 30-degree vertex angle. After multiple reflections, it formed a dodecagon
(30° 75° 75° isosceles triangle mirror, the effect is as shown on the right).
Kaleidoscopes are made using the imaging principle of plane mirrors, which produce images through the refraction of light.
Kaleidoscope Story:
In 1816, Scottish physicist Sir David Brewster invented the kaleidoscope. Brewster was mainly engaged in optical and spectroscopic research. He was very fond of optical experiments in his childhood and spent most of his life on his favorite optics.
Once, when he was using multiple mirrors to study the properties of light, he saw the scene after multiple reflections in several mirrors placed opposite each other, so he put some floral paper in the cavity formed by the mirrors. As a result, He saw some symmetrical patterns, and every time he changed the position of the flower paper, the pattern would change.
In order to keep the pattern changing, he placed three angled mirrors in a cylinder, and then placed floral paper between two layers of glass at the end of the cylinder.
As the angle of the mirror in the triangular mirror changes, the number of images also changes; the images overlap to form various patterns, and you can see the changing patterns by constantly turning the kaleidoscope.
In this way, he created a kaleidoscope that allows you to see different patterns by simply turning it. Kaleidoscope became an unexpected success overnight.
This little thing that can produce wonderful patterns when it moves can be regarded as the "television" of its time. Once a pattern disappears, it takes centuries for the same combination to appear.
The invention of the kaleidoscope has been listed as a major scientific invention and has been recorded in history. There are also some beautifully crafted kaleidoscopes in museums.
Because the kaleidoscope is both a beautiful work of art and an educational toy that can cultivate thinking and observation skills, it is deeply loved by children and adults, and is constantly being renovated in peoples hands. For example, some people put 30 to 40 glass vials like church spires in a kaleidoscope, filled them with oil, and soaked glass particles, fine coral pieces, shells, and sand particles in the oil. When these small sealed glass bottles are moved, the sparkling particles inside the bottles will rise and fall. In addition to these things, there are also tightly tied filaments, horse hair, and various spiral and curved small things. In this way, making the kaleidoscope rotate is like watching a wonderful ballet performance.
