New Gadgets And Innovations From Science Service Bulletin
Portable refrigerator uses dry ice with separate compartments for solid carbon dioxide and ice water. Miniature pulse jet engines power model airplanes. A fuel nozzle, ignition system, and starting battery complete the warm up. A night light uses neon tubes under a shaded edge without glare. A plastic chest shield simulates breathing in a lightweight portable iron lung. A modified bowling pin whistles after impact with an air passage and cork core. A kitchen scraper uses a bottle cap as a tool. A fruit picker device mounts on wheels to straddle a tree with movable ladders. For more information, send a stamp for Gadget Bulletin 328.

Interlacing Threads of Gas and Sun Corona Study
Science Service reports on the sun's outer atmosphere or corona studied via eclipses and coronagraphs. Dr. W. O. Roberts and researchers at Climax Colorado reveal how prominences spicules and interlacing gas threads form the solar envelope. Observatories and instruments on mountains enable daily corona observations and potential weather links. The piece traces instruments from Lyot to Menzel and Outlook for global coronagraph networks by the 1950s.
