Hello Dear Readers today Dot and Mae are playing with a Kaleidoscope – do you know what those are?
Wikipedia describes a kaleidoscope like this:
A kaleidoscope is a tube of mirrors containing loose colored beads, pebbles or other small colored objects. The viewer looks in one end and light enters the other end, reflecting off the mirrors. Typically there are two rectangular lengthwise mirrors. Setting of the mirrors at 45° creates eight duplicate images of the objects, six at 60°, and four at 90°. As the tube is rotated, the tumbling of the colored objects presents the viewer with varying colors and patterns. Any arbitrary pattern of objects shows up as a beautiful symmetric pattern because of the reflections in the mirrors. A two-mirror model yields a pattern or patterns isolated against a solid black background, while a three-mirror (closed triangle) model yields a pattern that fills the entire field.
Modern kaleidoscopes are made of brass tubes, stained glass, wood, steel, gourds and most any other material an artist can sculpt or manipulate. The part of the kaleidoscope which holds objects to be viewed is called an object chamber or cell. Object cells may contain almost any material. Sometimes the object cell is filled with liquid so the items float and move through the object cell with slight movement from the person viewing.
Kaleidoscopes are lots of fun. You can look at them over and over and see such lovely patterns and colors – you never know what shapes or patterns you will see next!
If you would like to play with a kaleiscope, but you don’t have one at home, Dot and Mae have found a couple online that are fun to play with!
This site is called Zefrank.com and you can make kaleidscope patterns – then clear it out and make another one! FUN! There is also a kaleidoscope painter program that’s a little less complicated – but interesting looking none the less!
