One of the best parts of being a kid is just hanging out with family and friends.

Generally, kids don’t have responsibilities to be anxious about (unlike silly adults). That’s why they can feel free to come up with awesome dance routines, play games, roller skate, and just waste time in epic fashion. During their own hangout sessions growing up, brother and sister Billy and Emily discovered they had an incredible talent.

They spent years dedicating their time to becoming better and better on wheels. Now? They can perform a routine that’ll make you speechless.

Their routine might make you dizzy.
