The BT Young Scientists Exhibition is opening this afternoon at the RDS in Dublin, involving more than 1,000 students.
More than 60,000 people are expected to visit the exhibition – the largest of its kind in Europe – over the next four days.
5 hundred and 50 projects are competing for this year’s title.
For the second year in a row, more projects made the shortlist to exhibit at the RDS in Cork – at 118 – compared to 97 from Dublin.
Ronan MacGaoithín from Coláiste Ailigh in Donegal worked with his brother, to investigate if GPS could take over from Hawk Eye in judging whether points are scored in GAA games.
