 St. Andrews in Scotland is famous for many things. It is the home of golf. It is also famous for being home to the university, where Britons Prince William and Kate Middleton met for the first time as students. Now, scientists at the university have developed a small device that shows whether whisky is real. One of the scientists, Praveen Ashok, places a drop of whisky on the glass. Laser light shines through the drop, and a computer sensor says immediately whether it recognizes the liquid. This one is real, but when you add water, the computer warns that it is not the real thing. Manufacturing whisky is a big business. The famous brand names are costly to buy. Campbell Evans is with the Scotch Whisky Association. Scotch whisky can only be made in Scotland, and it's vitally important to protect the industry so we don't find fakes appearing around the world. Because somebody buys a fake product and doesn't like it, they may never buy the genuine article ever again. We have five in-house lawyers whose job is to stop anybody who puts brown liquid in the bottle and pretends it's whisky when it's not, and we can have up to 70 court cases and they go at any one time. Kishan Dalakia of St Andrews University says the new device could even save lives. We think it's a real public safety and health concern. You know, people will lose their lives. For example, in India, many people lose their lives because people tamper with alcoholic drinks and toxicology, and they make additives that basically have, I think, resulted in people's deaths. The main issue now for the inventors is to find a factory to make the device. I'm Jim Tenor.
