It was a dream come true for a 15-year-old-scientist.
He couldn't contain his emotions after winning the world's most prestigious science fair award.
Jack Andraka won $75,000 in scholarship money and beat out 1,500 entries from 70 countries.
"I was just freaking out and screaming and crying," he told INSIDE EDITION.
Incredibly, this teenage science whiz discovered a revolutionary new test for detecting pancreatic cancer. The same disease that claimed the lives of actor Patrick Swayze, and Apple founder Steve Jobs.
That was back in 2012. So what has this teen innovator been up to?
He's still working in the basement lab of his Maryland home where he first began developing his revolutionary cancer detecting discovery. "This is my mad scientist lab in the basement!" he said.
His mom Jane has always been very supportive of his experiments.
"We would just let him go down here and tell him not to blow up the house," she told INSIDE EDITION.
Jack said his discovery can also detect ovarian and lung cancer, even heart disease.
"That's one of the coolest things, is this can detect the cancers in the earliest stage," he explained.
His test is fast and cheap.
"This cost three cents and takes five minutes to run," he said.
Jack's potentially life saving test earned him a one on one with President Obama. Jack told INSIDE EDITION, "Pretty much one of the most amazing times in my life."
That giddy kid we saw a few years back has matured into a poised speaker, captivating large audiences at TED Talks, and even the Colbert Report in 2013.
Colbert: You own this?
Jack: Yeah, I have the international patents on this technology.
Colbert: So cha'ching right, cha'ching!
Jack: It's actually not about the money for me, it' really about saving as many lives as possible.
Now, Jack's has written a new book, "Breakthrough." Each chapter contains different experiments budding young scientists can do at home. He also opened up about having been bullied and the struggle to fit in.
"I definitely don't see myself as a genius kid, I just see myself as an ordinary teenager," he said.
