A set of Dublin twins are getting ready to represent Ireland on the international stage in a new sport.
"Stacking" is part of the PE curriculum in a growing number of schools. It involves up and down stacking of specially designed cups.
Ten-year-old Mark and Owen Byrne from Walkinstown will represent Ireland at the World Sport Stacking Championships in Germany next month.
The duo were among the fastest eight to qualify at the All Ireland Championships in Dublin earlier this year.
Not bad, for boys who have been at the sport for just 18 months.
