Hot Wheels Loop Stunt Performed In Real Life Shows Science At Its Finest

If you're as annoyed as I am by Earth's gravity and how it relates to cars, this one is for you. The death-defying insanity-fest that is the X Games held an event where a real-life Hot Wheels race loop was constructed before two high-performance cars were sent through it.

Tanner Foust and Greg Tracy are the two drivers that were insane enough to think that their 1.3 tonne performance cars could successfully complete the 18-metre loop-de-loop at this year's X Games.

The cars had to enter the loop at a minimum of 77 km/h to successfully complete the loop, while simultaneously trying not to collide with each other. The results are truly astounding. [YouTube via Jalopnik]

    Magnets?

    I like gravity. It helps keep my car on the road.

    Amazing stunts! Too bad they were so badly shown in this vid. They edited together the most context absent shots so you can't really see the true magnificence of the action- jumps are shown from behind so you can see how high they were the spin is shown from the cars and from the ground so you can't see how cool it looked to the crowd, etc.

    I'm disappointed, they didn't jump back to 1955...

      They would have had to be travelling at 88 miles an hour to do that!

    At 7G those cars must way close to 7tonnes! No wonder they bounced when they landed, the suspension would have been so tight to hold that weight through the loop.

    Take that laws of physics! Your puny powers are no match for ... even more ... laws of ... physics.

    In terms of the science, does anyone know what the equation is that tells you that 77kph upon entering a loop is sufficient to hold 1.3 tonnes of car against the track? I'm a little rusty on tangential force calculations.

    Saw it on the news last night.... and my mind was blown. So awesome!!!!

    the weight is irrelevant to the velocity required to keep contact throughout the loop, the only factor is the radius of the loop itself. the centripetal acceleration has to exceed the acceleration due to gravity, and the calculation of the centripetal acceleration is mass independent. http://en.wikipedia.org/wiki/Centripetal_force.

    Wow, only 77kmph. That's not that fast.

    They do this everyday
