17-year-old Paige Brown of Bangor, Maine won the 2016 Intel Science Talent Search for her innovative method of cleaning polluted waterways using dollar-store hair clips, a block of foam, and seaweed! For her ingenious invention, the Mighty Girl was the recipient of the prestigious science fair's "Global Good Prize" and a $150,000 college scholarship. Paige's invention makes it possible to inexpensively remove excess phosphorus from water in order to prevent harmful algal blooms which kill fish and other plant life.
With her research, Paige wanted to tackle a widespread problem called eutrophication, in which a nutrient, often phosphorous, seeps from decaying organic matter like dead leaves and causes an excess of algae growth in water. The excess algae uses up the available oxygen leading to animal and plant die-off and it can also produce a toxin that's harmful to humans. To remove extra phosphorous from water, Paige used a gel called "alginate", which she extracted from seaweed, and mixed it with aluminum and magnesium. She placed balls of the compound in the mouths of dollar-store claw hair clips and stabilized them in blocks of foam. She discovered that one gram of her compound has the potential to "clean 254 liters of water contaminated with 0.5 mg/L phosphorus" which she adds "would be very contaminated water to begin with” -- all for $3 worth of materials! And, as an added bonus, after the collection, it can be "planted" in the ground to act as a slow-release capsule to provide phosphorous for crops that need it as fertilizer.
With such promising results, Paige is eager to continue researching the potential applications of her invention and will next study its effectiveness at removing E. coli bacteria from polluted water. And, to other aspiring young scientists, Paige can't recommend the experience of participating in STS highly enough. “It’s an incredible opportunity... The kind of connections I can make here are going to be crucial further down the line,” she says. “It’s an opportunity I wouldn’t trade for anything in the world.”
