Kaleidoscope

We relate the word "kaleidoscope" to a changing world. But in Greek, "kaleidoscope" means 'beautiful' , not "changeable" view. Do you want to see the world through the kaleidoscope? Look into the tube. Isn't that beautiful?

To understand how a kaleidoscope works look through it on a lamp, but from the other end. There are only three mirrors inside, sometimes even two. The green slivers placed between two diaphragms, of which one is mat and the other transparent, resemble leaves. The pink slivers resemble petals of a flower while the red ones resemble a stalk.

The kaleidoscope was the favourite entertainment on the court of Queen Victoria in England over 100 years ago.
