Talking on P55 Work in pairs. Imagine you are two inventors and you have designed a new product,which you want to sell. First, you need to decide on your product; Second, you will have to explain how your product works. Third, you need to show that people will be willing to use it. Use the descriptions on P56. ZH: I understand you have invented something that will be really useful to families and single people alike. XG: Yes, indeed. It’s a self-cleaning shirt, which works as you wear it. We made one that would work as soon as you put it on. It uses the heat from your body to attract water vapor from the air. ZH: Isn’t that a little uncomfortable? XG: No. We thought about that. We gave the material a special coating to keep water away from the skin and to store it in the fibres. When they are full of water the shirt begins to clean itself. ZH: How does it do that? Is there soap powder in the fibres too? XG: Not really, but we thought the fibres could do that job if they had a special anti-pollutant in them. It mixes with the water and removes the dirt from the shirt. The dirt is then carried into the air as the water turns back into vapor. ZH: How will you know if the shirt is doing its job? 1.
