Like two other new materials introduced recently-Nitramon. du Pont's "foolproof" explosive (TIME, Feb. 4), and Solene, a solidified gasoline developed at New York University (TIME. July 15) - tempered glass lends itself to spectacular demonstrations. Last week it was unharmed after a 2-lb. steel ball and a11-lb. bag of steel shot had been dropped on it from six feet, after a pane of it had been placed on an ice cake and molten lead poured on the top surface, after a torsion machine had warped a sheet of it like so much cardboard...

It is almost foolproof in operation and all he will have to do is tend to his plants...
...Faster heat radiation means higher temperature, interfering with nearby coils and resistors. 2) Prime requisite for handling short waves is good insulation, which glass provides and steel does not. 3) Glass tubes are not fragile but rugged, almost foolproof, used in millions of cars and trucks on all kinds of roads. 4) Vacuum is preserved better in glass than in metal. 5) Transparency of glass facilitates inspection, often betrays faulty operation at a glance...
Having repeated and completed these tests over many months in many places, E. I. du Pont de Nemours & Co. last week announced' development of a powerful new explosive tentatively named nitramon, called it "foolproof," "the ultimate in safety...
...visits do not always have the best results. I seem sometimes to place an evil spell on any machines in which I would take a special interest. They may break down or stop. Once, to my surprise and dismay, I was dropped in a lift; another time a supposedly foolproof stamping machine ejected 40 unstamped letters for my benefit. The threads of looms at times break as I approach them, but, in spite of these odd occurrences, I am glad that employers are ready to welcome me in their midst...
