...grass" farmer need do is scatter seed some time in the spring, then go off to a love-in for 60 to 80 days. When the female Cannabis sativa bears its resinous flowers, the farmer simply plucks the plant and dries the top portion in the sun, an oven, or - as one Chicagoan prefers - in a Laundromat dryer set at "Cotton." The cuttings are then "manicured" by forcing them through a screen (No. 12 mesh, a protective screening used in prisons and detention homes, does nicely). Roll, ignite, puff - and off to Cloud...
...these substances are polarized-containing an uneven distribution of positive and negative charges-they align themselves with the direction of an electric field. Microwave fields reverse themselves rapidly; to keep up with them, the polarized molecules must oscillate constantly. This oscillation produces a rise in temperature. In a microwave oven, for example, the electric field completely permeates a potato, instantly heating the moisture in its center as well as in its skin: it is evenly baked within five minutes. Microwaves have already been put to work precooking chicken before freezing, drying freshly painted surfaces and dehydrating lumber, paper and potato...
After class Blitman joins the happy throng headed for Mr. Bartley's Burger Cottage. Known as "the Spa," Bartley's combines the best qualities of a Ricky Nelson malt shop and a large brick oven. Cheery red and white signs tumble across two walls. There are too many to read, so don't try. They are all about hamburgers, anyway; Mr. Bartley's offers twenty different kinds, ranging from Hawaiian to Saute'ed Mushroom...
...background that would prove most useful in community development. Between them they were able to teach first aid, child care, swimming, carpentry and auto mechanics at the Casa del Obrero of Manta; in their spare time they managed to organize neighborhood cleanup campaigns, fight bubonic plague and build an oven for the local school's hot lunch program...
...medicine is only the beginning. Heat-resistant shields, developed to protect spacecraft plunging back into the earth's atmosphere, have led to the production of Pyroceram dishes that can go from the housewife's freezer to oven without cracking. The increasing complexity of astronavigation has fostered the development of swifter and smaller computers that find no end of applications on earth. The fuel cell used to supply electric power for Gemini spacecraft is being developed for commercial use, and its production of electricity from oxygen and hydrogen without burning hydrocarbons may be one answer to the smog problem...
