We tend to take for granted the humble containers in which food, beverages and almost everything else comes to us.

In fact, these containers often represent the end product of a complex and intriguing process in which materials, machines and people are mixed. One of the most complicated is that of aluminum, and you'll find the entire story exquisitely told in two booklets and a colorful wall poster.

"The Story of Aluminum" tells all about this remarkable metal, which offers an alternative to the "tin" can, and which shows up in hundreds of other applications. You'll learn about these in "Uses of Aluminum," and you'll see the entire process by which aluminum is made in a wall chart called "Aluminum and Alcoa." All these materials are available on request from ALCOA, 1501 Alcoa Bldg., Pittsburg, Pa. 15219.

SAVE ON DRUGS - When you're sick you want relief, and when the doctor prescribes a pill, you sometimes have the option of making the cure less costly. The way to do it is with generic drugs - drugs prescribed by their chemical names, rather than their brand names. Obtain a free copy of "Generic Drugs: How Good Are They?" by writing the Consumer Information Center, Pueblo, Colo. 81009.

A DNA FREEBIE - Everyone is fascinated by the intricate chemical code that carries information from one generation to the next, but few really understand how the DNA molecule performs. Anyone junior-high-school age or older will understand the clear, concise description provided in "The Fact of Life," a colorful and well-illustrated booklet offered by the Public Relations Dept., FB, Eli Lilly and Co., Indianapolis, Ind. 46206.
