Model Molecules. General Motors' Charles Franklin Kettering and L. W. Shutts had great fun constructing a model of what Professor Donald Hatch Andrews (Johns Hopkins chemist,G.M. consultant) told them a molecule of water must look like. They took two steel balls of equal weight to represent hydrogen atoms. For the oxygen atom they took a third steel ball weighing 16 times as much as each ''hydrogen atom." They also built spiral springs whose tension in relation to the weight of the three balls resembled the electrical forces which hold a molecule of water together. They joined...
...descent. Now the great yellow cotton bag, of 14,000 cu. ft. capacity, is laid carer fully out on the field by 100 workmen, sweating under a blazing sun. The shroud lines which support the spherical aluminum gondola are straightened out with meticulous care. In the cool of night hydrogen is fed from cylinders into the envelope. In less than an hour the inflation is finished. The bag is one-fourth inflated, bulges at the top like a mushroom...
...Considering the circumstances-that is, a submarine operating on the surface, with her hatches open, and her commander, and others, on deck, and showing no intention of submerging-the most probable cause of sinking is an internal explosion. All submarines give off an odorless gas, hydrogen, when charging batteries, and this gas, when mixed even in small proportions with air, forms an extremely powerful explosive mixture, which might be ignited from a number of causes inside the boat. The resulting explosion might easily have so damaged the hull as to sink the submersible immediately. In our own Navy there have...
...Being bled of her hydrogen a few days after arriving from Germany, borrowing the Shenandoah's helium supply for her first flights in the U. S. (Because the gas was scarce in those days, the Shenandoah had to stay at home while her new sister went forth...
Filled only to 35,000 cu. ft. because of scarcity of hydrogen, some of the bags had difficulty in leaving the ground. The City of Detroit dragged her basket along the field, barely cleared it, came down with a gas-leak 10 mi. away in the Missouri River, luckily upon a tiny island. All the others fought electrical storms through the night. Second to land next morning was the Chevrolet entry (at Jamestown, N. Dak., 410 mi.) after her crew had thrown overboard all ballast including spare clothing to let the basket clear a high tension wire. An hour later...
