Kaleidoscope
Kaleidoscope
Kaleidoscope (/kəˈlaɪdəskoʊp/) is a tube of mirrors containing loose colored objects such as beads or pebbles and bits of glass. As the viewer looks into one end, light entering the other end creates a colorful pattern, due to the reflection off the mirrors.
Etymology
The term "kaleidoscope" is derived from the Ancient Greek words καλός (kalos), "beautiful, beauty", εἶδος (eidos), "that which is seen: form, shape" and -σκόπιο (skopio), "to look to, to examine", hence "observer of beautiful forms".
