问题：温水真的会比冻水更快结冰吗？这是伪科学还是真实的？（我没法做实验 
这是伪还是真实的？（我没法做实验）
回答：所谓姆佩姆巴效应从1963年开始传了40多年，全世界包括家在内的人都深信不疑！然而最近中国上海一初中的学生竟然经科学的试验数据证明，姆佩姆巴效应是不存在的！！！（最新媒体报道：中国电视台10频道科学栏目2005年11年21日）我一下子找不到汉语资料，只有英语资料：Hot milk freezes faster than cold milk. Is that real? 热牛奶要比冷牛奶先结冰，真的吗？      你有没有自己制作过牛奶冰淇淋呢？如果有你会发现在冰箱里，热牛奶要比冷牛奶先结冰。这就是著名的“姆潘巴现象”。在近半个世纪后，本市3名高中女生向这个世界疑题发出挑战…… “No. Under the same condition, hot liquid（液体） doesn’t freeze faster than the cold one,” reads a recent scientific（科学的） report. Three local senior high schoolgirls, with the help of their teacher, tried to refute（驳斥） the law of the Mpemba Effect（姆潘巴现象） and their result was sent to the expert panel（专家小组）. If passed, their research will be the first ever to give a reasonable（合理的） explanation（解释） for the Mpemba Effect, and close the nearly-half-century- old heated（激烈的） debate（争论） in the world.Starting with doubts  Ye Shasha, Yu Shunxi and Dong Jiawen, three little scientists first learned about the Mpemba Effect on the book Hundred Thousands of Whys during the days of their primary school.  “I’d never doubted the Mpemba Effect before because I thought everything was right in the textbooks during my childhood（童年）,” said Ye Shasha. She also won the second prize of Future Engineers Forum of World Engineers’ Convention last year.  It was this doubt that led them to join forces. Once Huang Zengxin, their teacher of science and technology, told his doubt about a paper that supported（支持） the Mpemba Effect in a lecture, the girls were encouraged（鼓励） by the same feeling and a scientific research group came into being.Ice cream “feast”  >“We have gotten along with these three-color ice cream for several months,” Ye Shasha smiled, “I don’t think I will eat ice cream again.”   But it was the ice cream that helped them out of their toughest time. In a series of experiments（实验）, they found the same result that ice cream, under same conditions, freezes faster than milk. It was the starch（淀粉）in ice cream that quickened the freezing speed.They hope to contact with Mpemba  The whole winter vacation, over one hundred experiments and tens of thousands of data（数据） led to the result that the Mpemba Effect won’t happen.  Three girls expressed their common wish, “If possible, we want to contact（联系） Mpemba himself and do the experiment with him.” 摘自上海学生英语报
