Sounds like an early version of the hygiene hypothesis Poor Kids More Immune to Germs SURPRISING facts about the numbers of Canadian school children who get germ diseases such as measles and scarlet fever were reported to the Canadian Public Health Associations. Contrary to what might have been expected, children from the better districts of [...]
THE day of the talking book, the talking newspaper and the talking magazine is foreshadowed in the recent invention of a French machine which reads from a strip of film-like substance any speech that is recorded on it.
Why So Many Murders in U. S.? NO LESS than six American cities, homicide statistics disclose, have more murders in proportion to their population than any other city in the world. The chief reason for this American murder habit statisticians believe, is the prominence given to crime in newspapers and movies. The second is the [...]
A MECHANICAL boon to bridge fans, which will place the favorite indoor sport of 25,000,000 men and women on the same basis as big-league baseball, has been perfected by a Racine, Wisconsin, inventor.

I’ve always wondered why my knee joint’s weren’t as supple as I’d have liked. I always I assumed that it was because I’m lazy and shiftless, but apparently it’s just because I’m a Jew. Damn you gentiles with your supple knees! Does Knee Flexibility Test Race? A NEW method of determining racial origin has been [...]
I think I’m going to have to call bullshit on this one. Unless that’s actually a Kangaroo… Texas Rabbits Roped Like Steers THE jackrabbits they sure grow big in the Lone Star State. If you need graphic proof just take a look at the photo at the right. Believe it or not, but that thing [...]

TRANSPORTATION of city inhabitants through subway or overhead tubes on endlessly moving belts, providing more speed and comfort than our present systems of passenger service, loom as a possibility, according to Norman W. Storer, engineer of the Westinghouse Electrical Co., who has developed the idea. As described by Mr. Storer, the system is an arrangement of continuous trains or belts of cars, running on parallel tracks. There is a stationary loading platform along the entire course of the system.
Broncho Has Bucking Mechanism THE display which attracted most attention in a recent Shrine parade held in San Francisco was a bucking broncho that only the mechanical-minded could figure out. The vigorous and realistic bucking of the broncho was created by setting the wheels of the chassis on which it was mounted 1-1/2 in. off [...]
Will Power Operates Gramaphone YOU can take this story as seriously as you want to. It came to us as perfectly legitimate stuff and here it is: Major Raymond Phillips, O.M.E., late member of the Inter-Allied Commission of Control, claims to have evolved apparatus which will cause a gramaphone or kettle to function entirely by [...]
WHAT is more embarrassing to a housewife who boasts of her cooking than to have her mashed potatoes turn out black, or to have her guest slice into a
EVER wonder how some of those remarkable pictures you see on the talkie screens are producedâ€”the kind, for instance, in which you seem to be falling from a mile in the air right down into the heart of New York City? The series of photographs at the right will give you an idea of how it's done.
That’s a cute boat but, do sandals really make your feet bigger? Youthful Skipper Hits Off 10 m.p.h. Clip on “Aquacar” A TWIN-PONTOON “aquacar” has solved all navigation problems for young Billy Barrud, of Lake Arrowhead, Calif. Eight paddles on each side wheel enable him to back up or speed ahead, merely by turning the [...]
THAT mechanical ingenuity is a distinct and highly profitable asset in times such as this, when millions of men are out of work, is proved conclusively from four stories which have emerged from news of the past month. These four stories each told of mechanics who capitalized on their talents, the services offered to the community varying from operating a freak "water taxi" to insulating ancient refrigerators. All the schemes to knock off extra cash, or even provide the entire family revenues, are gathered here, and we pass them along to you as money making hints.
THE long, exhausting search of scientists for a method of harnessing the rays of the sun has yielded the solar machine illustrated in the artist's drawing above. Operation of the machine is based upon the principle of contraction and expansion of tungsten wires. These wires are arranged lengthwise of a revolving drum, and the sun's rays are directed against them by means of a parabolic mirror on each side.
by Earle W. Gage Hoover or Rooseveltâ€”which will be our next president? Millions of voters will cast their ballots in November on a new ingenious machine which will baffle crooked voters and minimize the delay in learning who has been elected. Here is told the fascinating story of this machine and of its forebears devised by inventors of ancient times. TRULY, magic-working mechanical wizardry shall select the next president of the United States, as millions of voters march to the election booth in November to cast their ballots. "50,000,000 Votes for President!" is the popular slogan. Thanks to the genius of the engineer, who has perfected voting machinery of marvelous accuracy and precision, it is now possible to tabulate the greatest popular vote in history, announce the result and flash the news to the remotest hamlet in less than sixty minutes after the polls close.
Make Trailer From Defunct Auto OLD automobile bodies that have been consigned to the junkyard can still do a lot of good in the world, for they can be pressed into service as very substantial trailers. The chief operation you will have to perform on the auto is the cutting ofF of the front at [...]
X-RAY shadowgraphs have heretofore displayed only two dimensions, height and width, but with the recent development of the "cross-eyed" X-ray a third dimension, depth, is added, making the image appear like a sculptured skeleton. The three-dimensional X-ray is the invention of Prof. Jesse W. Du Mond, a Pasadena, California, scientist, who calls his instrument a "Stereofluoroscope." The main element of the machine is a pair of X-ray tubes whose beams, directed against the patient as illustrated in the drawing above, intersect in the body, thus casting shadows in two different planes.
by DALE R. VAN HORN A Hallowe'en party might be defined as a nocturnal orgy of nonsensical abandon. In other words, an affair when any goofy trick is in order. If you want to show your guests some real fun perform the stunts described here and then won't be a single moment of boredom ON HALLOWE'EN Eve you can stage all the goofy stunts you have been wanting to exploit for a long time. Nothing is too low-brow for the occasion. It is the one time of the whole year, not even excepting New Year's, when you can forget worldly cares and the weight of adult responsibilities, and have a thoroughly good time.
MOTION pictures are being given another eye. Recently in the Academy of Sciences, in Washington, Dr. Herbert E. Ives, internationally known engineer, produced motion pictures that gave the illusion of depth, making them appear like views in old-fashioned stereoscopes.
Machine Translates 1000 Words MACHINES can do almost everything but actually think, and a mechanism recently devised by a French language teacher almost does that, for it can translate one thousand words of French into English and vice versa. The mechanical translator employed in teaching conversational English to Paris police, is seen below. On it [...]
Mechanical Radio Man Talks, Sings, Walks, and Rolls Eyes A YOUNG engineer in Berlin, after four years of work, has just perfected what is the strangest type of man ever to appear on this earth. The thing, shown in the photo at the left, outdoes Frankenstein in everything save looks. So perfect is it mechanically [...]
To think, I’d always believed that redshift was caused by the doppler effect. How silly of me. Actually the light just gets really tired! (You would too if you’d traveled for 13 billion light years without a single vacation day). And of course blueshift occurs when the light is really happy or excited, like when [...]
by M. W. MEIER The tank is a powerful weapon, but the faithful horse can still outfight it in many situations encountered on modern battlefields. Here is told the cavalry's side of the story. YOU may not know it but Uncle Sam has the finest cavalry on earthâ€”pitifully small though it is. It may lack the swank, color and picturesqueness of that of other nations but what it may lack in fancy-drilling ability it more than makes up for in equipment, firing-power and maneuverabilityâ€”the things that really count in war.
Hot Water From Waste Lamp Heat ILLUMINATION engineers are well aware of the deplorable fact that no device wastes energy like an electric light. Only 4 to 5 per cent of the “juice” is transformed into light, the remaining 95 per cent being wasted in useless radiant heat. Now comes a Swiss engineer with an [...]
Exciting! Gym Horse From Hot Water Tank A GYM horse that can stand the weather and delight youngsters can be made and set up in half an hour by the method shown in the accompanying photograph. The pipe is readily driven into the ground, after connecting to the tank, of course. A little concrete may [...]
Everyone who has seen Frank Buck's "Bring 'Em Back Alive," that amazing movie of jungle life, is asking the question: "How did they ever film that spectacular battle between a Bengal tiger and a 30-foot python? Was it faked? How did the cameramen happen to be on the sceneâ€”and how did they escape with their own lives?" Read the answer in this article. WHO won â€” the python or the tiger? This is the question which is bothering thousands of folks who have seen Frank Buck's startling movie of jungle life, "Bring 'Em Back Alive," and who have been vividly impressed by the incomparably spectacular scenes shown therein where a Bengal tiger, dreaded king of the jungle, battles the flashing coils of a deadly rock python thirty feet in length.
Wow. I think all instant photographers owe a great deal of gratitude to Edwin Land for helping save them from this fate. Cameraman Wears His Darkroom PITY the poor news cameraman. In other days he carried his camera slung over his shoulders, but now he must wear it. This innovation in cameras, shown in the [...]
