This was a total revolution. You really don’t want to know where they held their cigarettes before this was invented.

Cigarette Holder for Nudists
Faced with the problem of carrying cigarettes when no pockets were available, a delegate to a recent nudist convention devised the holder shown at right. The leather case is strapped to the leg by means of an elastic band.

Three-Wheeled Auto Makes Speed with Low Fuel Cost
Resembling a tiny inclosed model, a three-wheeled automobile designed in Germany has a closed top and doors like bigger cars. Although the vehicle does not consume much fuel, it is said to attain a speed of ten miles an hour on good roads. Its size enables it to be operated where more cumbersome machines might find difficult traveling. It is claimed that, owing to the small size of the car, the government places no tax on it and permits its use without a driver’s license.

I wonder what kind of “comfort and entertainment” the provided to “seaman strangers”…

“THE DAUGHTERS OF THE SEA”

By LAWRENCE Wm. PEDROSE

FOR the purpose of making more comfortable and pleasant the hours spent in their home ports by the masters, mates, and pilots of the Pacific, and developing radio broadcasting to their ships while at sea, wives, daughters, and sweethearts of manners living at Seattle have formed an organization called the “Daughters of the Sea.”

The Daughters of the Sea plan to bring the home closer to the ship, and the radio will be their chief means toward that end. The club has undertaken the fitting up of quarters on the top floor of one of the city’s tall buildings, and is furnishing them with a library, comfortable chairs, smoking accessories, and marine glasses, so that seafarers may watch from the windows the ships making and leaving port.

Surprising Tests WITH Household AMMONIA

Simple Experiments and Home-made Apparatus Extend Your Knowledge and Speed the Work You Can Accomplish in Your Own Laboratory

by Raymond B. Wailes

IT IS surprising what the amateur chemist can do with a fifteen-cent bottle of ordinary household ammonia.

Being a mixture of ammonia dissolved in water, this pungent-smelling liquid offers an ever-ready supply of ammonia gas for the home laboratory. Even at room temperature, the gas is released from the liquid. By heating it, the experimenter can obtain the gas in larger quantities.

Strictly speaking, household ammonia is not ammonia at all, but ammonia water or ammonium hydroxide. Although ammonia can be liquefied, it is a colorless gas at normal temperatures. The fact that it dissolves readily in water makes the manufacture of ammonia water possible.

Pointer
The Laser Pointer projects a visible bright red spot of light several hundred feet under normal lighting conditions-great for lecturers with slides. The $800 helium-neon laser has an output of 0.5 mW—not enough to harm eyes or body, says RMF Products, Box 413, Batavia, III., 60510.

Building Dreams of Steel In San Francisco Bay

by C.W. Geiger

They said it couldn’t be done—span the Bay and Golden Gate with bridges, but San Francisco did it And threw in a great Exposition to boot. This story tells how the impossible is accomplished.

THE intricate and wondrously knit glittering spans of the world’s two greatest bridges across the Golden Gate and Oakland Bay, and a magic isle of Atlantis—dripping with all the miracles of an international exposition, is what San Francisco is preparing for your coming in 1938-39.

The site of the Exposition lies in the white-capped San Francisco-Oakland Bay area, midway between the two cities, on shoal land located just north of the adjoining Yerba Buena Island. And this year 385 acres of shoal will be filled in to provide the site for the Exposition. By the end of 1936, when the fill is completed, architectural plans for the buildings will also be finished, so that actual construction will begin with 1937.
