Here's the Hot Wheels Double Loop Dare Stunt from X Games

The pair went through the 20-m-tall loops, which replicate a similar Hot Wheels toy track set, hitting 84 km per hour and pulling 7Gs in the process. Nifty.

The successful stunt gets marked down as a Guinness World Record, next to other amazing feats like the World's Largest Collection of Rubber Ducks.
