I am a speaker

Fionn Ferreira

I am very motivated and enthusiastic, I enjoy innovation and cool science, especially when things go bang! I have entered the BT Young scientist competition many times and love inventing and tinkering at home! I have won awards with my science projects at both national and international science fairs. I can communicate science, I enjoy tinkering on projects, I am confident and can speak in front of people, I am very motivated and can carry through projects effectively. I can code in C++ and think it is really interesting to automate my home with Arduino and Raspberry Pi projects.



I am a confident and engaging speaker. I have given many talks and lectures about science, my story and my projects too and have experience including head lecturer at Schull Planetarium. I like to get people motivated about sustainability, innovation and science. If you would like me to speak at your event, please contact me or fill out this form.

Good Communicator

I enjoy speaking to people and giving them knowledge. I have gaind valuable experience in this at Schull Planetarium, where I am the curator and head lecturer.


I am fascinated by the garden and nature.


I love new ideas and projects! I enjoy a good challange.


I get excited about science and innovation. I have done many award winning science projects. Including one winning the Google Science Fair 2019


I have achieved a high level at playing the trumpet and have played in several orchestras.


An award winner at the student enterprise competitions, I like thinking of new business ideas and following them through.

    I am really pleased to say that I have started a National Geographic Open Explorer blog to share my story and my project progress.
    I would really appreciate it if you were to follow me and my progress.

  • Winning Google Science Fair 2018-19

    I am so proud to have been named the winner of the 2018-2019 Google Science Fair.
    I cannot wait to be mentored and engage with scientists with my project.
    The Google Scence Fair gave me a uniqe experience of Google and where I got to meet many different scientists and engineers.
    I have made friends and love what a wonderful, eductational community this fair has created.

  • Google Science fair Global finalist!

    I am so pleased to have been selected as one of the top 20 projects of the 2018 Google Science Fair from thousands of applicants to travel to the Google Headquarters and compete for several prizes this coming July 2019.

  • TG4 at Schull Planetarium

    I really enjoyed working with TG4 for a part of their documentary celebrating 50 yers since Apollo 11 landed on the moon. I found it interesting to present facts about the moon and our planetarium in Irish. The documentary will be shown on TG4 during July.

  • A minor planet was naimed after me!

    I would like to thank the MIT Lincoln Laboratory for choosing my project from the intel ISEF projects as one which has contributed to science. This means that a dwarf planet (fionnferreira) has been named after me!
    I am delighted to have this great honour.

  • Summer term starts at Schull Planetarium

    Schull planetarium will be open with starshows given by Fionn Ferreira this summer 3 times a week.
    I really enjoy being able to design and give the planetarium shows, which greatly develops my communication and interpersonal skills.
    As well as being the planetarium curator, I do all of the graphic design and lecturing.

  • Schull student Fionn Ferreria zaps microplastic pollution

    The sunday times, June 10th 2018

    An Irish teenager has created a liquid that can remove microplastics from water, writes Laoise Neylon. The tiny plastic particles have become a significant source of pollution in seas and oceans, and often end up in fish that people eat.

    Fionn Ferreira, 17, from Schull, Co Cork said that his invention removes microplastics by magnetising them. “Essentially it is a process that works with ferrofluid, a magnetic liquid,” he explained.
     Both oil and plastic are non-polar, which means they do not possess a negative or positive charge, and so in the presence of water they will attract each other and stick together. Ferreira adds oil and magnetite, an iron ore, to the water and this solution attracts the microplastics. “Then I can pull it all out with a magnet,” he said.

     Industry, households, water-treatment centres and mineral-water companies could potentially reduce the microplastic contamination of water by about 87%, he believes. Sophisticated filtration systems capable of removing microplastics do exist, but are not being used because they also remove other items from water, including minerals. Because of its liquid nature, Ferreira thinks his invention could be scaled up and used by industry to reduce pollution. “I’m thinking about a continuous flow system,” he said.
     “There would be a layer of ferrofluid and contaminated water would flow through it.” Any traces of magnetite and vegetable oil that remain would be entirely harmless to the environment, he said. The World Health Organisation (WHO) is currently conducting a review of existing evidence on whether consumption of microplastics is harmful.

    It has yet to establish whether they are present in water at concentrations harmful to human health. Ferreira, a student at Schull Community College, recently won two awards for his idea at the Intel International Science and Engineering Fair. Patent developer Intellectual Ventures also gave him its Insightful Invention Award. It is hoped that Ferreira’s invention can be scaled up to allow water-treatment facilities to remove microplastics at a relatively low cost. Nathan Myhrvold, founder and chief executive of Intellectual Ventures, said: “There are a lot of engineering challenges still to be solved to do that, but the use of chemical and electromagnetic separation techniques together is a potentially powerful combination.” He added that the volume of plastics littering the ocean continued to grow every year, and a huge source of this pollution was municipal wastewater and stormwater. “Any technology that could efficiently allow plastics to be captured from these wastewater flows before they are discharged would be a big win for the environment.”

  • Meeting with Nathan Myhrvold

    I was thrilled to be presented with an all expenses paid trip to Seattle this June by the company Intellectual Ventures. This company works with inventors and scientists in their labs to deletions ground breaking technologies and innovation.
    I got to meet and discuss my project with the founder and CEO Nathan Myhrvold at their headquarters this June.
