Kaleidoscope

A kaleidoscope is a special toy that is like a tube with mirrors and colorful things inside. When you hold it up to your eye and twist it around, it makes beautiful patterns and shapes that look like a colorful symmetrical picture.

Inside the tube, there are small pieces of glass, plastic or other things that have different colors and shapes. They are called "beads" or "gems." The mirrors are placed in a special way, so that when you move the kaleidoscope around, the beads inside create beautiful reflections that make beautiful patterns.

It works by reflecting the light and colors in different ways. The beads or gems inside the kaleidoscope shine in the light and bounce around the mirrors, creating all kinds of shapes and colors.

There are all kinds of kaleidoscopes with different shapes and sizes, and some even have lights and sound effects. It is a fun toy that you can use to make pretty pictures and patterns and to explore the science of light and color.
