麦当劳汉堡放14年未变样 A US man has shown off a 14-year-old McDonalds hamburger that looks the same as the day he bought it. 一个美国人近日展示了自己14年前买的一个麦当劳汉堡，这个汉堡和当初他买的时候一模一样。 David Whipple, a California man, has saved a fast-food hamburger he bought in 1999 for 14 years. ? David Whipple, from Utah, had originally planned to keep the burger for two months in order to show friends how its preservatives（防腐剂） would maintain its appearance.? ? But, after accidentally leaving the product in his pocket for two years, Mr Whipple decided to keep the burger for even longer to see how long it could continue looking normal.? ? It wasnt on purpose, Mr Whipple told US television show The Doctors.? ? I was showing some people how enzymes work and I thought a hamburger would be a good idea. And I used it for a month and then forgot about it.? ? It ended up in a paper sack in the original sack with the receipt in my coat tossed in the back of my truck and it sat there for, I dont know, two or three months. ? However, Mr Whipples experiment was then forgotten after the coat was tossed in a closet.? ? My wife didnt discover it until at least a year or two after that. And we pulled it out and said oh my gosh, I cant believe it looks the same way.? ? Doctors on the CBS show noted that aside from the pickle（泡菜，盐卤） disintegrating, the burger showed no signs of mould, fungus or even a strange odour（气味，声誉）.? ? Mr Whipple admitted that at one point he had considered selling the burger via online auction site eBay.? ? But, despite bids reaching close to $2,000 (￡1,300), he and his family decided to keep the product for educational use.? ? He now admits he uses the burger to convince his grandchildren not to eat junk food from restaurants such as McDonalds.? ? Its great for the grandkids to see. To see what happens with fast food, he said.
