Kaleidoscope

I’m sure many of you don’t know what this is a Kaleidoscope, but you will know it if you look at these videos below:

A kaleidoscope is a tube of mirrors containing loose coloured beads, pebbles, or other small coloured objects. The viewer looks in one end and light enters the other end, reflecting off the mirrors. Coined in 1817 in English by its inventor Sir David Brewster, the word “kaleidoscope” derives from the Ancient Greek καλ(ός) (beauty, beautiful), είδο(ς) (form, shape) and -σκόπιο (tool for examination), and it literally translates to “observer of beautiful forms.”

Now you know 😉
