　　Polyester is now being used for bottles. ICI, the chemicals and plastics company, believes that it is now beginning to break the grip of glass on the bottle business and thus take advantage of this huge market.

　　All the plastics manufacturers have been experiencing hard times as their traditional products have been doing badly world-wide for the last few years. Between 1982 and 1984 the Plastics Division of ICI had lost a hundred and twenty million dollars, and they felt that the. most hopeful new market was in packaging, bottles and cans.

　　Since 1982 it has opened three new factories producing Melinar, the raw material from which high quality polyester bottles are made.

　　The polyester bottle was born in the 1970s, when soft drinks companies like Coca Cola started selling their drinks in giant two-liter containers. Because of the build-up of the pressure of gas in these large containers, glass was unsuitable. Nor was PVC, the plastic which had been used for bottles since the 1960s, suitable for drinks with gas in them. A new plastic had to be made.

　　Glass is still cheaper for the smaller bottles, and will continue to be so unless oil and plastic become much cheaper, but plastic does well for the larger sizes.

　　Polyester bottles are virtually unbreakable. The manufacturers claim they are also lighter, less noisy when being handled, and can be reused. Shopkeepers and other business people are unlikely to object to a change from glass to polyester, since these bottles mean few breakages, which are costly and time-consuming. The public, though, have been more difficult to persuade. ICIs commercial department is developing different bottles with interesting shapes, to try and make them visually more attractive to the public.

　　The next step could be to develop a plastic which could replace tins for food. The problem here is the high temperatures necessary for cooking the food in the container.

　　There are two factors which determine an individuals intelligence. The first is the sort of brain he is born with. Human brains differ considerably , some being more capable than others. But no matter how good a brain he has to begin with, an individual will have a low order of intelligence unless he has opportunities to learn. So the second factor is what happens to the individual the sort of environment in which he is brought up. If an individual is handicapped environmentally, it is likely that his brain will fail to develop and he will never attain the level of intelligence of which he is capable.

　　The importance of environment in determining an individuals intelligence can be demonstrated by the case history of the identical twins, Peter and Mark. Being identical, the twins had identical brains at birth, and their growth processes were the same. When the twins were three months old, their parents died, and they were placed in separate foster homes. Peter was raised by parents of low intelligence in an isolated community with poor educational opportunities. Mark was reared in the home of well-to-do parents who had been to college. He was read to as a child, sent to good schools, and given every opportunity to be stimulated intellectually. This environmental difference continued until the twins were in their late teens, when they were given tests to measure their intelligence. Marks I. Q. was 125, twenty-five points higher than the average and fully forty points higher than his identical brother. Given equal opportunities, the twins, having identical brains, would have tested at roughly the same level.
