Meet 17-year-old Paige Brown. She's a senior from Bangor High School, and she's created a way to pull destructive phosphorus from a stream by using seaweed gel with aluminum and magnesium. She created a filter to clean polluted water!

Her device doesn't just remove phosphorus, but also puts it into the ground to fertilize it.

Her invention won her the Global Good Prize of $150,000 in college tuition at the Intel Science Talent Search.

Polluted water endangers billions around the world, and her invention has the potential to help them.
