How can you make dance so acrobatic that it makes go people "wow"? Ask Kailey and Kelianne and their dance troop, who certainly have that "wow" factor in them.

Just a few weeks back, they uploaded this dance routine on YouTube and choreographed Justin Bieber's "Sorry."

But there's a twist: the entire dance happens on hoverboard.

The sheer balancing and acrobatic movements that these dancers have on this tiny hoverboard is simply stunning.
