PROTIP: Don't watch the POV footage right after lunch.
Record Setting Gravity-Fed 10 Loop Hot Wheels Track

This is a video of the folks from Youtube channel 5MadMovieMakers setting what they believe to be the world record for gravity-powered Hot Wheels loops, with a respectable ten. Is it actually the world record? I have no clue, but it doesn’t seem like it would be that difficult a record to break provided you have enough Hot Wheels track and a steep enough hill. And a Hot Wheels car — don’t forget about the car. Otherwise you’ll wind up like me the time I set out to break the world record for most hula hoops in motion at once but forgot to bring my hoops. “And pants.” So embarrassing. “But you stood there gyrating anyways.” I felt like the judges at least deserved a show.

Keep going for the video, which includes POV footage from a GoPro car.
