Teenage star tackles Eau Rouge on a skateboard
There are just two words needed to sum up the magic of Belgium's Spa-Francorchamps circuit - Eau Rouge.
The left-right-left combination sweeps down from La Source and then steeply uphill to a blind summit which Michael Schumacher describes as "seeing a big mountain in front of you".
But just how steep is that famous slope? The BBC TV team and Red Bull put their heads together and came up with a unique solution - plonk a teenage skateboarding star on the crest of the hill and watch him fly back down.
The call was put in to European champion Axel Cruysberghs, who handily happens to be Belgian, and the 14-year-old warily took up the challenge.
"I don't know about the cars but it is very steep," said Cruysberghs. "Maybe I'll go fast down there because it's so long. This could be the fastest I've ever been on a skateboard."
Cruysberghs pondered all this while nursing a broken right wrist in his lap. Um, was he a little worried?
"I don't know. We'll see. It's something crazy."
Once the track was cleared of traffic in the fading early evening light, Cruysberghs set off up the slope with a final pep talk from Jake Humphrey.
The 14-year-old turned up to look at him; "It's pretty steep, no?" The TV presenter's advice? "Don't look down."
Wearing a backwards chequered baseball cap and skinny black jeans, the European champion loomed over the summit and took the plunge.
He dipped his right foot to the famous tarmac to brake, using his left to steer and balance the board as he zig-zagged back down to the mouth of Eau Rouge.
Cruysberghs was unfazed, murmuring a brief "Ohh, uhh" as he reached the bottom with a top-speed of 26mph. In his first run, he covered a marked out 15-metre stretch of incline in 1.47seconds.
So after setting a Formula 1 first by becoming the first person to skate down the famous Eau Rouge does he fancy cutting short his fledging skating career for a more lucrative move to F1?
"No, it's too fast."
