This brother-sister-duo began skating as kids. And when they took to the reality show's stage, no one knew what to expect from the act...
As the act gathered momemtum, judge Alesha Dixon could barely look on... The hosts, Anthony McPartlin and Declan Donnelly who watched from the wings, wanted them to stop and yet couldn't take their eyes off the stage.
Their "fresh spin on roller-skating" video, posted two months, ago has over 15 million views on YouTube. And that should be enough information for you to watch this video.
So let this performance make you dizzy for all the right reasons. And please don't try this at home.
