A 15-year-old student who invented a flashlight(手电筒) 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(晶体管).

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 s«w 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 hope 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.

Fifteen is such an awful(糟糕的) age, I should know. I really wish I were eighteen. If you are an adult, you can be your own boss. People like my parents and my teachers are always telling me what to do. You know what I mean. “It’s time for bed, Sandy.” Or “ Sandy, you’ve watched too much TV for one night.” “Sandy, stand up straight.” “Sandy, you must improve your handwriting.” Sandy this, Sandy that. No one tells adults when they go to bed or not to watch TV. Besides, adults get to wear what they like... Now it’s going to be great to be an adult. Don’t you agree?

I’m Sandy’s mother. Having a fifteen-year-old daughter isn’t always easy. Right now, we’ve got a problem. Our neighhour, Mrs. White, wants Sandy to look after her pet dog for one week. Sandy really wants to do it, but I’m worried.  She’s too young and inexperienced. Well, I will never be able to relax knowing she is all alone with a dog. I’ve tried to explain my feelings to her, but she won’t listen. She keeps telling me that the Whites live very near, so she can ask for help. She insists that Mrs. White won’t ask her to look after her pet dog if she doesn’t think Sandy is old enough. She says I’m “babying” her and I hate to see her mad at me. What should I do?
