We looked at one invention called "movement enhancing gloves" and they were developed by finalist Charalampos Loannou of Greece for his grandmother who has arthritis and has difficulty moving her fingers.
"So you can see how fast it reacts when I am just touching the sensor, the model pushes the finger for me," said Loannou.
Elif Bilgin, 16, is from Turkey. She created bioplastics from banana peels -- no kidding. She says, "You dip it, you boil it, you puree it and you add some chemicals in it." Her creation would be used for insulation. "Well, the plastic could be used for...I have a short demo here. The electricity runs through the cable, but it doesn't run through the plastic. So it could be used in the insulation of cables."
This year there we're 18 finalists -- 12 were young women. Esha Maiti from San Ramon came up with a better understanding of tumors and Venket Sankar from Cupertino did his research on how to protect endangered species during large infrastructure projects. Unlike other science fairs, this one reaches out to students around the world.
"Talents is universal, but opportunity is not so we are trying to knock down the doors of that by putting the science fair online," said Mary Lou Jepsen, a science fair judge.
I don't know about you, but I am always curious to know what past winners have done with their experiments and how their lives have changed. I found Shree Bose -- the winner of the first Google science fair, which was held in 2011. She did her research on drug resistance and ovarian cancer.
"I'm now at Harvard. I'm a sophomore this year and I'm, working in a new lab and I'm working in sort of the same subject field with metabolism and energy and cancer," said Bose.
This year the winner gets a $50,000 scholarship.
