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 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.

We can't remember clearly since when we have started to take our mobiles to a dinner table. This happens a lot,especially when we eat out. Once a dish comes,instead of lifting our chopsticks,we take out our mobiles and click. Later, we post the photos onto Weibo or Wechat,waiting to be "liked". Then we check our mobiles from time to time during the meal,to see whether we get "liked" or not. We just cannot leave our mobiles for only a meal.

Does that sound familiar to yours? Do you do that often? If not,how do you feel when others do that when having dinner with you?

A recent study suggests that what we are used to doing is not so good. Spending time taking photos of food makes the food less pleasant. To test this,some researchers did an experiment. Some people were asked to take photos before they could enjoy food. As a result,it showed that the more photos they took, the less delicious the food seemed to them.

Besides the scientific result, there are also some other bad influences of taking photos of food before meals. After posting the photos onto the Internet,one will not be able to control himself and check his mobile many times. "Does everyone like my photos" It seems that your mobile secretly calls your name all the time, even when you are with real people.

So, next time you go out to have dinner with your family or friends, how about not taking photos of food? Let the food be delicious as it is and share your life with people around you. Trust me. It will be a wonderful time.
