how to DIY kaleidoscope.
Everyone played the kaleidoscope when they were young. A small eyepiece can see the color combination map of different colorful combinations. Here's a chance to make a play for your own children at home, or buy it from a DIY manufacturer. A kaleidoscope is an optical toy. As long as you look into the tube, a beautiful "flower" will appear. Turn it around a bit, and another pattern of flowers will appear. Constantly turning, the pattern is constantly changing, so it is called a "kaleidoscope".
With multiple reflections of light between the two mirrors, a kaleidoscope can be made. DIY kaleidoscopes purchased from children's toy manufacturers allow children to paint their own colors and patterns, eliminating the difficulty of preparing and making materials. After finishing the production, you will see beautiful patterns.
