A 15-year-old student who invented a flashlight(手電筒) getting power from the holder's body heat is going home today from California with a big prize and a chance to do further research.

Ann Makosinski was the only Canadian among the four winners at Google's international science competition. Thousands of young scientists from around the world took part in the competition.

Winning the science and technology competition was "a surprise". Ann said, "I think it will have a great influence on my future."

Ann thanked her family for encouraging her interest in science and said that her first toy was a box of transistors(晶體管).

Ann's prize includes $ 25,000 and a "once in a-lifetime expericnce" from Google for her Hollow Flashlight, which has no moving parts or batteries.

The idea for the invention came from seeing unwanted batteries and her friend's experience. When Ann visited a friend in the Philippines, she saw the friend couldn't study when it became dark because there was no electricity or light. She saw the need for a flashlight that has no batteries - Hollow Flashlight.

In her project, Ann wrote "I made two flashlights that do not use any batteries or harmful materials. They do not create any noise and will always work. The flashlight needs at least a 5℃ temperature difference between the holder's body and the environment around to produce light."

A video of Ann explaining how she creatcd the flashlight has been watched more than 1.4 million times on the Internet.

Though Ann was successful, she has not made a decision about her career path. Ann hopes that she can find a way to join her love of film and science together.

The four winners were chosen from 15 final competitors from eight countries. The competition attracted thousands of students in 120 countries.

I used to watch him from my kitchen window. He seemed so small as he played through a crowd of tall boys on the playground. The school was across the street from our home and I would

often watch the kids as they played during break.

I remember the first day when I saw him playing basketball. He ran circles around the other kids. He managed to shoot jump shots from their heads and into the net. The big boys always tried to stop him but no one could.

One day, I met him and asked him why he practiced so much. Without a moment of hesitation he said, "I want to go to college. The only way I can go is to get a scholarship. I am going to play college basketball. I want to be the best. My daddy told me if the dream is big enough, the facts don't count.

I watched him through those junior high school and into senior high school. Every week, he led his school team to victory

One day in his senior year, I saw him sitting in the grass with head in his arms. I walked across the street and sat down in the cool grass beside him. Quietly I asked what was wrong. "Oh, nothing," came a soft reply, "I am just too short." The coach told him that he would probably never get to play for a top ranked team-much less offered a scholarship. So she should stop dreaming about college.

He was heartbroken and I felt my own throat tighten as I sensed his disappointment. I asked him if he had talked to his dad about it yet. He told me that his father said those coaches were wrong. They just did not understand the power of a dream. He told him that if he truly wanted a scholarship and that nothing could stop him except one thing-his own attitude. He told him again, “If the dream is big enough, the facts don’t count.”

The next year, as he and his team went to the Northern California Championship game, he was offered a scholarship. Finally, he was going to get the college education that she had dreamed of.
