However, an optimal configuration that produces the full effects of the kaleidoscope was not recorded before 1815. Bradley's New Improvements in Planting and Gardening (1717) described a similar construction to be placed on geometrical drawings to show an image with multiplied reflection. In 1646, Athanasius Kircher described an experiment with a construction of two mirrors, which could be opened and closed like a book and positioned in various angles, showing regular polygon figures consisting of reflected aliquot sectors of 360°. Multiple reflection by two or more reflecting surfaces has been known since antiquity and was described as such by Giambattista della Porta in his Magia Naturalis (1558–1589). History A comparison of the mirror constructions of Kircher (left) and Bradley (right) Patterns when seen through a kaleidoscope tube Rotation of the cell causes motion of the materials, resulting in an ever-changing view being presented.Ĭoined by its Scottish inventor David Brewster, "kaleidoscope" is derived from the Ancient Greek word καλός ( kalos), "beautiful, beauty", εἶδος ( eidos), "that which is seen: form, shape" and σκοπέω ( skopeō), "to look to, to examine", hence "observation of beautiful forms." It was first published in the patent that was granted on July 10, 1817. These reflectors are usually enclosed in a tube, often containing on one end a cell with loose, colored pieces of glass or other transparent (and/or opaque) materials to be reflected into the viewed pattern. Hope your wife likes it when completed.For other uses, see Kaleidoscope (disambiguation).Ī kaleidoscope ( / k ə ˈ l aɪ d ə s k oʊ p/) is an optical instrument with two or more reflecting surfaces (or mirrors) tilted to each other at an angle, so that one or more (parts of) objects on one end of these mirrors are shown as a regular symmetrical pattern when viewed from the other end, due to repeated reflection. If you google kaleidoscope you will find companies that have layered woods that are turned, that reveals different layers of wood underneath and leaves lots of color woods to choose from and creativity is limitless. I made one from a longer piece but the same size front to tip is not quite as appealing. The ends should be made a little larger to help it feel better. I made the body from three quarters thick white oak and a strip of mahogany. Very worthwhile project and easy to do on a wood lathe. I tried thinning it with alcohol but that did not seem to improve performance. The items are suspended in glycerin and that is available at any drug store on the shelf. The object container can hold anything you put in it. He shows how to cut a small ridge inside the pvc where the lens fits by tight fit and epoxy glue. It has an object box, which is a piece of PVC 2 inches in diamater and one half inch long. Duxbury, Run time 114 minutes, available at: The DVD is very thorough, he offers plans but I did not need plans the DVD is so very complete in every detail. Hi Jim, I made this Kaleidoscope from a DVD that I bought at an estate sale for one dollar !!!! The DVD may still be available: by James N.
