...argument: these single-celled animals live in countless billions in the sea. When they die, their silicic, spherical skeletons sink to the ocean floor, form a radiolarian ooze. An explosion such as the H-bomb would blow them skyward, heating them past 1,710° centigrade, at which temperature silica melts. But they would harden again at the lower temperatures of the atmosphere and, being feather light, would float on the wind across the Pacific -to strike windshields...
Skidless Shine. A tough, nonslippery floor wax is being test-marketed by E. I. du Pont de Nemours & Co. For use on both hardwood and linoleums, the Safety Floor Wax contains tiny, gripping particles of Du Font's Ludox (colloidal silica) which snub the forward motion of a shoe hitting the shiny floor, bring it to a safe and sure-footed stop.. Price: $1.29 a quart...
...Bell crystals are grown in thick-walled steel "bombs" filled with a water solution of alkaline material (see diagram). At the bottom is a layer of finely ground quartz (silica). A small quartz crystal (it may be only a sliver) is suspended near the top. When the bottom of the bomb is heated to 750°F., and the pressure raised to 15,000 Ibs. per sq. in., the ground quartz dissolves. Its molecules diffuse through the solution. When they reach the cooler top of the chamber, they deposit one by one on the "seed," building it into a perfect...
