    Alice Lee is a high school student studying at a private school. She is doing some voluntary work at an after-school program to help students from poor families.

    On the first day of her work, she noticed that many kids were lining up for free sandwiches and fruits. She was surprised. One of the organizers explains that many of these students don't get enough to eat at home. So a school lunch or an after-meal might be the most food they would get all the day. She has also been told that some hungry kids can receive free lunches, but others are only allowed reduced-price meals, and those students' families have to pay for the part of their food.

    Lee was shocked, she decided to offer help to those who are suffering from hunger, "I want other kids to understand that if you see a problem, you don't have to wait to be an adult to fix it," says Lee. She and a group of friends are using their programme skill to create a new app called Food of Thought, which will allow parents, students, and even kind-hearted strangers to donate money to lunch accounts for students in a nearby school.
