LIGHT CARRIED IN BUCKET

FREEZE IT IN LIQUID AIR WONDERS DEMONSTRATED NEW YORK, Dee. 6. The latest achievements of practical science—-including the popping of corn by radio and the transportation of liquid air—were demonstrated by two scientists of the General Electric Company. Tiie, Merchants' Association of New York witnessed (he performance, givdn by .Messrs. L. A. Hawkins and E. L. Manning at a luncheon. Another of the demonstrations was to show production of short waves at high power, causing electrons inside a glass tube to glow brilliantly and to give off many colors. These ultra-short waves produce fever in the. hitman body if one is exposed lo Ulom for any length ot timeAil interesting experiment was the placing of popcorn kernels between idee trodos constructed of jass glars con. taiuing cold salt, water, (lie. idea being to heat, the moisture iii the kernels and cause them to burst as in popping over a flame. TRAXSPORTINC; LIGHT Apparently they will lie carrying light around soon in buckets, if the present successes continue, for light, frozen stiff by being clipped in liquid air. was brought into a. room in a. container, and released, thus allowing it lo bo heated slowly. Gradually the, light thawed out and changed from deep yellow to purple. Then waves of light,, charged With color, flitted about liko the celestial sportings of the Aurora" Boreal is. The, smallest voice in the world was also audible, as an electrical charge was giiven off by an electron. It was magnified millions of times by a high-power amplifier. Miniature explosions were audible. SOUND MADE VISIBLE Then a phonograph was started. An electrical device was attached. Instead ol a sound, the attached A'eon light glowed rt'i\. Sound was being made visible. The light, which apparently glowed steadily, was in reality flickering in t uiic with the vibrations of the phonograph disk by allowing the Aeon glow to fall on a. sensitive photo-electric cell on. another piece of apparatus which caused, music lo pour forth from an attached loud speaker. The visible sounds could be cut off entirely by placing the baud between file Neon lube and the photo-electric cell. Striking a match demonstrated another tovin of electronic discharge. # A combined rattle and roar was heard. The (hyratron, one of the most powerful valves for controlling] large amounts of power, was controlled by lighting a match before the eve of anolber photo* electric cell. When the match lighted, a ICOO wall I nlli wired 1.0 the llivratron glowed brilliantly. As long its the light of Ibe large lamp played on the electric eye the lamp remained burning. When a demonstrator walked between the electric eye and the 1000-watt lamp ii was swili bed off automatically by the apparatus. The demonstration showed how large electrical machines could bo

stalled or stopped by sunlight or a ray ol artificial light played on the delicate surface of the photo-electric cell.
