The acrobats from Cirque du Soleil are always impressive. Even watching a Cirque du Soleil acrobat PRACTICE video is impressive. The one that is making the rounds now, really made me nervous. David J. Rimmer and his circus partner Steph uploaded a video this weekend of the two of them practicing on what is called a “teeterboard”. The tricks in the air are definitely cool, but it is when one guy flips and the other guy runs to the opposite side that things get scary. I was convinced that somebody was either going to crack their skull or somebody was going to take a hard shot in the crotch from the teeterboard! If you want to see the finished product, these two guys perform in the Cirque show called Corteo.
