Miss Jones, head of El Dorado Inventions, has been manufacturing automobile mufflers since 1913 when her ears were first assailed by an unmuzzled Ford in a Moline garage. Her idea for the airplane muffler she gleaned from contemplation of a grease-vapor exhaler set into the wall above a restaurant stove. Another of her products is a 2-lb. electric flatiron. Fiftyish, Miss Jones believes in the ability of women over 40, substitutes them for men at workbenches in her machine shops whenever possible...
...scientists had already learned that by using other gases they could get other colors-argon & mercury vapor for blue, the same combination in a yellow tube for green, carbon dioxide for white. The gases are confined in the tubes at low pressures (5 to 10 millimetres, compared to 760 millimetres in the sea-level atmosphere). The gases are made to glow by an alternating electric current flowing through them. Because of the penetrating quality of the infra-red rays given off, neon lamps are used as fog beacons, airfield lights...

Specifically he was shooting helium atoms (alpha particles derived from radio active thorium) from a shuttered, camera-like box into a tube containing nitrogen and water vapor. The helium atoms traveling at a clip of 11,000 mi. per sec. smashed into the nitrogen atoms. The force of the impact caused the atoms to merge for an instant to form fluorine which immediately broke down, with explosive force, into hydrogen and oxygen...
