Aston Martin driver Lance Stroll was bizarrely covered by a BIN BAG during Friday's practice session at the Canadian Grand Prix.
Canadian Stroll is the home candidate for this Sunday's race in Montreal. The 24-year-old has achieved three podiums in his blossoming career but is still to bag his maiden win, with Aston Martin's mechanics working hard to help him break that duck in his hometown.
Stroll's preparations for Sunday's race included him being covered by a bin bag in the garage before going out to practice. The incident left many Formula One fans baffled, but Sky Sports reporter Ted Kravitz was on hand to explain the method behind the madness.
Kravitz said: "The mechanics are waiting because the engineer hasn't given the go for the car to leave the garage yet, and they need to put on the flow-vis paint... so they can tell exactly what the air is doing to prove what the wind tunnel is telling them.
"It's a crucial part of Formula One aerodynamics. It's quite basic, but they do need to spray this paint on the car, just to see the lines where you get.
"Because you don't want to get it on Lance Stroll's crash helmet, and all the rest of the bits of the car, then you've got to cover it with half a bin liner - which has been stretched over Lance's head! So Lance can't actually see!"

The bin bag was over Stroll for around a minute-and-a-half before the flow-vis paint was eventually applied. At that point, Kravitz laughed: "There we go! They're doing it now."
Yet Kravitz's entertaining commentary didn't stop there. There was a bit of rain floating around the Circuit Gilles Villeneuve during Friday's training session, which led the reporter to joke: "He [Stroll] might need that bin bag to shield himself from the rain!"
Stroll went on to be ninth fastest in Friday's practice session, with his Aston Martin team-mate Fernando Alonso coming in fourth. It was a good day for Mercedes who registered a on-two with Lewis Hamilton in first and George Russell in second.
Hamilton, who hasn't won a race for more than 18 months, told reporters: "It was OK. Probably the bumpiest circuit we have been on for a long time. But bit of a strange day. Missed the first session, felt really bad for all the fans. I love driving this track. It's mega.
"The car didn't feel bad but I think we definitely have some work to do. Not the greatest but not the worst. It is feeling pretty decent but it is just bumpy. I think everyone is having struggles with the bumps. We just have to improve our ride control and a bit of balance through the corner and I think we'll be all right.
"The car is massively better than last year. The rear end is not but overall it is a step forward and I am definitely feeling the improvements we brought in Monaco."
