Rhys Millen, Steve Millen's most daring nephew, will again attempt to do a backflip in a specially-designed truck during New Year's Eve. The back-breaking practice video of him failing makes us nervous.

According to Millen, who will be performing the stunt outside the Rio All-Suite Hotel & Casino in Las Vegas for the cameras, he has to be within one mph and one inch to make the truck backflip and not destroy him. We'll be crossing our fingers he does better than he did in the first practice run shown here. [EXPN]
