What is kaleidoscope definition?

A kaleidoscope is a cylindrical device with mirrors and coloured glass or other embellishments inside. When you look through the eyepiece at one end, you'll see a multitude of patterns and colours reflected in the mirrors that change as you turn it. The term kaleidoscope comes from the Greek words kalos which means "beautiful," eidos which means "shape," and skopein which means "to look at." It was invented by Scottish scientist Sir David Brewster in 1816 and quickly became popular as a toy and a tool for artists and designers. Nowadays, kaleidoscopes are still enjoyed by children and adults alike for their mesmerizing visual effects, and they are also used as teaching aids for math, science, and art.
