Manpower Flight Greatest April Fool Joke
PHOTOGRAPHS of a man flying through the air by his own power, the dream of scientists for centuries, completely fooled outstanding U. S. newspapers recently.
Captions on the photographs, coming from Germany, explained that Pilot Erich Kocher took off with a pair of rotor wings strapped to his chest. Kocher supposedly blew into a box which converted the carbon dioxide of his breath into fuel to operate the rotors. The turning rotors developed a vacuum ahead pulling the man through the air.
Scientist’s New Theories May Aid in Forecasting Weather Conditions
THEORIES which may explain the formation of the earth’s surface features, and eventually make it easy to predict both storms and earthquakes, have been evolved after years of research by Halbert P. Gillette, retired engineer and former instructor in science at Columbia University.
PLAYGROUNDS IN THE SKY
Here is MI’s hold plan to fight juvenile delinquency and get kids off the street.
THE scene is your city on a sticky, sweltering twilight in midsummer. Lights are beginning to wink on and kids are starting to gather in the streets after the evening meal.
A few years ago this was the danger hour in your city. You remember it well—the nightly muggings would begin about now and young girls would be afraid to venture out alone. Beatings were commonplace and gang wars, fiercely fought with knives and zip-guns, were a frequent occurrence. But things are different now.

Postpone Irrigation of Sahara
PLANS for turning the Sahara desert into a rich agricultural territory by means of diverting waters of the Mediterranean sea into depressions of the wasteland have been postponed for some time due to the death of the man whose idea and capital furnished the incentive. Dwight Braman, prominent American financier, was recently stricken with heart attack and died. It was his intention to begin the work of letting the sea into the desert this fall. American engineers and machinery were to be used, and following his return from Algeria before his death, Mr. Braman was highly enthusiastic of the possibility of making the “Sahara blossom like a rose.” Some of Mr. Braman’s friends are considering taking over the plans for the project.
Vision Perpetual Motion In This Rubber Band Engine
AN ENGINE run only by a single rubber band—does it have possibilities of perpetual motion?
Many who saw it on exhibit at the Hall of Science in Chicago’s Century of Progress Exposition believe it has. The engine, shown on the left, obtains its energy from heat directed on the rubber band. Many persons visioned the probability of substituting solar heat for the electrical heaters used in the exhibit. However, perpetual motion is an impossibility as the machine would run only during life of band.
