Can't remember whether this one has been posted here before, but it's pretty impressive.

Woah! I am impressed in a very big way! I wanna do that!

what is that called and where can i take lessons?

Incredible! I saw a similar earlier in the year, I wish that I had time to find it. I think it may have been the same girls at a different competition.
