A Tightrope Walker Went from the Top of One Semi to Another While They Were Driving Side-by-Side Down a Highway

A Volvo ad called 'The Ballerina Stunt' is racking up a ton of views on YouTube . . . but it has nothing to do with a ballerina.

It's a tightrope walker going from the top of one semi to another.  It's only about 20 or 30 feet, but she did it WHILE they were driving down a highway.

She also had a SERIOUS time limit, because the trucks had to go through a tunnel at the very end.

She starts at 1:50, then immediately falls but catches herself.  She makes it across at 2:50.
