WHILE all stunts described above are harmless, care should be exercised in the handling of the phosphorous and sulphuric acid (H2S04). Phosphorous when exposed to open air for periods longer than two minutes will burst into flame, therefore submerge it in kerosene when not in use. To protect your fingers from its effects powder them with chalk or talcum. A pair of small forceps may be also used, if available, in handling small pieces of the chemical. In handling the sulphuric acid be sure that none drops on clothing as it rots material.

THROUGH the magic of a gas filled tube that emits invisible germicidal rays when an electric current is passed through it, scientists hope to save us billions of dollars on our annual meat and bread bill. Dr. Robert F. James and Dr. Harvey C. Rentschler developed the tube in the research laboratories of the Westinghouse Lamp Co., after years of experimenting. The tube consists of a slender glass tube containing a special gas. When electricity passes through the gas it emits rays that will kill the microorganisms associated with food spoilage in packing plants and warehouses.

FROM Germany comes the news of another attempt to produce a plane of the rotating wing, or "paddle" variety. Unlike the well-known Dr. Rohrbach's paddle-plane design, the latest attempt to get away from conventional airscrews as a means of propulsion does not depend upon the paddles as a sole means of lift as well as propulsion. Rather, it seeks to adapt the paddle principle to an otherwise normal airfoil.

Out of Test Tubes Come Man-Made Products Smashing Traditional Fabrication Methods and Making Cheaply Available Shining Articles of Surpassing Utility. AS THRILLING as any Polar exploration is the day-by-day chemistry in America's laboratories. Here intrepid men with test tubes and beakers forge into the vast uncharted lands of science. More money is spent in this ceaseless venture than was ever dreamed of by Byrd or Stefansson. The cost is reckoned in millionsâ€”even, as with radium, in human lifeâ€”but the gains are worth the battle. For out of this pioneering comes new wonders to revolutionize industry and add comfort and enjoyment to living.
