EARLY April, I was walking between classes when my phone rang: I had been invited to the White House! I was going to exhibit (展示) my scientific work for the White House Science Fair. After school, I celebrated the news with my friend, Christine Yoo. I had been team leader on a research project with Christine that aimed to develop a device that could produce clean energy and remove oil pollution at the same time. For our work, we won the $100,000 prize in the Siemens Competition for Math, Science, and Technology. Now we were invited to the White House Science Fair to exhibit our efforts. We were beyond excited!
