Last month, 15-year-old Jack Andraka won first place at the world's largest high school science research competition, the Intel Science and Engineering Fair. The Maryland teen discovered a new method of detecting pancreatic cancer that's 28 times faster, 28 times less expensive, and over 100 times more sensitive than current tests.

Andraka's reaction to his big win is just as heartwarming as his discovery -- and now his unbridled joy is spreading across the Internet, collecting more than 125,000 views on YouTube. When his name is announced as the top winner, he runs onstage shrieking with joy and hugs the presenters enthusiastically. It's a moment of pure euphoria for the budding scientist, who modestly told Intel, "I did not think I was going to win a single award… It's unbelievable, I can't believe this is happening to me. This means so much to me."
