Analogous refraction demonstration experiment for the Circumzenithal Arc. [3] Here, it is mistakenly labelled as an artificial rainbow in Gilberts book [9] A water glass experiment (known at least since 1920, [9] cf. image on the right [10] [11]) may be used to create an artificial circumzenithal arc. Illuminating the top air-water interface of ...
A flask experiment known as Florence's rainbow is still often used today as an imposing and intuitively accessible demonstration experiment of the rainbow phenomenon. [85] [86] [87] It consists in illuminating (with parallel white light) a water-filled spherical flask through a hole in a screen. A rainbow will then appear thrown back ...
Beer bottles of different colors. Glass coloring and color marking may be obtained in several ways.. by the addition of coloring ions, [1] [2]; by precipitation of nanometer-sized colloids (so-called striking glasses [1] such as "gold ruby" [3] or red "selenium ruby"), [2] Ancient Roman enamelled glass, 1st century, Treasure of Begram
René Descartes had seen light separated into the colors of the rainbow by glass or water, [5] though the source of the color was unknown. Isaac Newton 's 1666 experiment of bending white light through a prism demonstrated that all the colors already existed in the light, with different color " corpuscles " fanning out and traveling with ...
Analogous refraction demonstration experiment for the circumzenithal arc. [9] Here, it is mistakenly labelled as an artificial rainbow in Gilberts book. [10] This approach employs the fact that in some cases the average geometry of refraction through an ice crystal may be imitated / mimicked via the refraction through another geometrical object.
When Glass pulled out the only dress she could find, dirty and rumpled, and wore it to tea, Mrs. Sutherland told her to go home and change and bring the dress back; Mrs. Sutherland thenlaundered ...

Pleasurable spectacles (faceted and coloured glass lenses) described and illustrated in I. Prevost's La Première partie des subtiles et plaisantes inventions (1584), [3] but the distortion of vision when looking through transparent objects must have been known much earlier (probably long before the use of reading stones) 1600s Mirror ...
