SECTION 3

I = Ilmar
D = Dawn

I: Hi, Dawn.
D: Oh hi, Ilmar.
I: I'm glad I've bumped into you. I've just found a great idea for the presentation we've got to do for Dr Banks next month.
D: What, the one on everyday objects?
I: Yes ... look at this article ... it's really interesting.
D: The aluminium coke can?
I: You know ... coca cola cans, soft drink cans. Look let's sit down here. Have you got a minute?
D: Sure ... I'll just get my bag.
D: OK, so you think we can get a presentation out of this article?
I: I'm sure we can. First of all we can provide some interesting facts about the aluminium cans that we drink out of every day.
D: Like ... ?
I: Well, here ... it says that in the US they produce 300 million aluminium Q22 drink cans each day.
D: Wow! 300 million!
I: Exactly. That's an enormous number. It says here "outstrips the production of nails or paper clips". And they say that the manufacturers of these cans Q23 exercise as much attention and precision in producing them as aircraft
manufacturers do when they make the wing of an aircraft!
D: Really! Let's have a look.
I: They're trying to produce the perfect can—as thin but as strong as possible.
D: Mmm ... this bit's interesting ... today's can weighs about 0.48 ounces: thinner than two pieces of paper ... from this magazine say.' Q24
I: Yeah, and yet it can take a lot of weight.
D: More than 90 pounds of pressure per square inch—three times the pressure of a car tyre. OK, I agree, it's a good topic. Q25
