Rainbows and Sun’s Green Flash (Oct, 1934)

Cool video from the ever awesome Sixty Symbols that shows the green flash.

Rainbows and Sun’s Green Flash

By Gaylord Johnson

FEW people realize that the famous green flash as well as the marvelous color effect called the rainbow, is explained by a principle which can be demonstrated indoors with the simplest of laboratory materials. In fact, not many persons have seen the green flash at all, either at sunset or sunrise, although it occurs frequently at sea or on land when the sun rises or sets in a clear sky on a level distant horizon.

Physical and Chemical Tricks! (Sep, 1936)

Physical and Chemical Tricks!

A few stunts the embryo scientist can present to his audience which are sure to mystify, astound or amaze them. All of the chemicals” used are readily available in the home, or in the corner drug store, and are inexpensive.

Chemical Engineering for Home Experimenters (Nov, 1939)

Chemical Engineering for Home Experimenters

By RAYMOND B. WAILES

HOW would you like to transform your home laboratory into a miniature factory for obtaining useful products from minerals, with yourself as its amateur chemical engineer? You can roast ores to obtain important metals, convert plain-looking stones into sparkling white crystals, operate a rotating kiln, and magically separate wanted minerals from unwanted ones by a flotation process.

Amuse Friends with CHEMICAL Stunts (Apr, 1934)

Amuse Friends with CHEMICAL Stunts

DO YOU like to dabble with chemicals? It was a hobby with Thomas A. Edison during his youth and formed the basis of an education that later brought thousands of new inventions into the world. Far from being a “dry” science, chemistry can be very amusing and entertaining. How many people would believe that you could pour a little drinking water into a china bowl and cause it to burst forth with flames several feet high—without the use of matches?

PRACTICAL AND MYSTIFYING HOME TESTS YOU CAN MAKE WITH IRON (Aug, 1933)

PRACTICAL AND MYSTIFYING HOME TESTS YOU CAN MAKE WITH IRON

By Raymond B. Wailes

MYSTIFYING and spectacular ‘effects give a keen interest to home experiments with iron and its compounds. The amateur chemist can make paint, produce molten iron from a simple mixture, and perform many other stunts that show why iron is man’s most useful metal.

Iron betrays its presence everywhere. Our blood gets its red color from the iron it contains. Soils, clays, bricks, and stones are colored by the iron in the earth’s crust.

A handful of ordinary nails or tacks will serve as the starting point for the home chemist’s experiments. From them he can produce several interesting iron compounds.
