CELLOPHANE MASKS SAVE DOCTORS FROM GERMS Cellophane masks for doctors and nurses are a recent innovation at a Los Angeles, Calif., hospital.

The masks may […]
Elevators travel under their own, self-contained power in a system upon which a New York inventor has just received a patent. Each car is suspended from a hollow drum containing a driving motor. Under control of the operator, the drum revolves and climbs a vertical series of rollers by means of a worm on its exterior, as shown in the diagrams.
Amazing new operation severs bones and then lengthens them gradually until a short limb attains normal proportions so limp vanishes MEN AND WOMEN, who once limped painfully through life because infantile paralysis or other disease had left them with a shrunken leg, now walk and work and play with all the ease and grace of normal, healthy human beings. A miracle of modern surgery has achieved for them the amazing feat of actually restoring the length of the deformed leg.

IF YOU own a goldfish, the chances are two to one it came from Martinsville. This southern Indiana town is the goldfish center of the world. Seventy-five million fish have begun life in the 600 ponds of its famous Grassyfork Fisheries. When I spent a week, not long ago, watching the work of caring for these miles of goldfish, 10,000.000 baby fish had just rolled from their round white eggs and were darting about ponds and hatchery tanks. For the older fish, men were cooking mush breakfasts in giant 7,000-pound boilers. Other employees were busy shooting weed-killing chemicals into ponds; stalking watersnakes, musk-rats, fish hawks; sorting, counting, packing goldfish and sending them racing across country in a giant truck that resembles a submarine and can carry 200,000 fish in a single load.
PERMITTED to peep behind the scenes in a giant food plant, a housewife would envy the speed and exactness of the modern machines used in preparing and packing food. The variety of these error-proof automatic devices is almost endless. In bakeries, massive, yet delicately adjusted mixers weigh and sift flour and measure water, mixing enough dough for hundreds of loaves of bread in one batch and assuring uniform taste and texture. The baked loaves are brought into position before a rank of dancing hack-sawlike blades that slice them in a flash, more nearly even than the most skilful housewife could do. Huge disks, rotating under corrugated rollers, knead spaghetti dough to a uniform consistency.
DIVING HELMETS WORN AS SWIMMERS LEARN STROKES Diving helmets are worn by pupils taking swimming lessons from a San Francisco, Calif., instructor who employs a radical new method of instruction. Wearing these helmets, the beginners frequently remain under water for long periods during which they study the swimming movements of the instructor and later attempt […]

by Prescott Lecky AT THE University of Iowa, a student recently hurst into a psychology classroom. Dramatically he gave details of a local kidnaping and cold-blooded murder. The criminal had been caught, had confessed, and a mob was forming near the county jail to lynch him. How many would go along and help the lynchers? At the height of the excitement, 200 students answered the following questions: How many would participate with the mob? How many would go along as spectators? How many would stay away?

AN ELEVEN-YEAR-OLD Texas boy is making good at a job so dangerous that only the hardiest men attempt it. He is a lion tamer, probably the youngest in the world. Armed with a cracking whip, a light chair, and blank cartridge pistol, he strides fearlessly into a cage crowded with ten young lions and, at a sharp command, makes them roll barrels across the floor, frolic on a see-saw and roar lustily in mock rage.
NOVEL FLAG FORMED OF COLOR-PRODUCING GERMS Colonies of bacteria provided the colors for a living American flag grown in Montclair, N. J., by a bacteriologist. The germs were made to perform their remarkable trick by tracing the outline of the flag on a shallow glass dish, with needles previously dipped in germ cultures. The dish […]
This looks like something out of Monty Python. PEASANTS USE VAULTING POLES TO GET TO WORK Vaulting with poles is a necessary part of the every-day life of Friesian peasants in northern Germany. There the low, marshy fields abound with drainage ditches. These are so numerous that the construction of foot bridges would be prohibitively […]
