An Irish teenager, Fionn Ferreira, has won a global science award for his project researching the use of magnetic liquid to filter microplastics from water. Google Science Fair challenged teens from around the world to solve a problem they care about using science, technology, engineering and maths.
Ferreira’s idea was the extraction of microplastics from the world’s oceans using a magnetic liquid called Ferrofluid. It is a non-toxic magnetic liquid that consists of oil and magnetite (iron oxide powder). In the presence of water, it attracts the microplastics because of the non-polar properties of both.
