I happen to be at United Square yesterday and everyone in the mall had their eyes glued at the centre open space as primary and secondary school children was having fun in this competition.
It's the High School Musical: The Ice Tour Shootout. It is a basketball shooting competition that involves 5 school mates in a team, each taking turns to shoot the ball and scoring as many points as possible in 2 minutes.
High School Musical is a hit amongst children. Have you watched the show on TV before? I enjoyed watching it!
