Which tire will roll down the ski jump fastest and jump the farthest? A Formula One tire? An enormous bulldozer tire? The smallest tire? This clip from Japanese television has made the rounds in years past, but the video source disappeared. We watched it again when it reappeared on Metafilter. Gotta love the lab coats, white gloves, and the surprising last jump.
So which of these six tires would you guess makes the biggest jump? And why?
Watch Ferrari’s F1 pit crew do a pit stop in around two seconds. We had to watch this multiple times so that we could figure out what each crew member’s two second task was and how they were doing it so quickly. Pretty incredible. From Autosport.com, via Kottke:
With three people per wheel, two jack operators, and a handful of mechanics fulfilling other functions, each pit crew comprises nearly 20 people…
They are drilled incessantly at both the factory and during race weekends, with hundreds of pitstop practices until the process is instinctive.
This sommerrodelbahn alpine coaster in Mieders, Austria, has been on our Must Do list since we saw this viral video a few years ago. The video above is from the same 2.8km (1.7 mile) summer mountain coaster and follows a brave 6 year old lad down 640 meters (2100 feet) into the valley, over fields and bridges, through the woods and countless switchbacks, all at a pretty quick pace!
Get a feel for what it’s like to ride the trains of Mumbai, India in Railway Days. Mumbai street photographer Mikhail Anand writes: “It covers the commute of a man trying to get to work, the several changes he has to make and his struggle as peak time hits the city in which he eventually disappears.”
Watch former F1 driver Lucas di Grassi do donuts at CES 2014 in an electric formula race car. He’s driving the Spark-Renault SRT 01E. It can go 140mph and from 0 to 62mph in three seconds. From The Verge:
The Spark-Renault is the first and only Formula E car for now, but ten teams are onboard for the inaugural 2014 - 2015 season, and each will have their own cars. For the first season, each car will be the same, but the series is designed as an open competition, unlike Formula 1. That means manufacturers will be largely free to push the boundaries with new technologies. In the process they’ll hopefully invent tech that will make it to future street-legal electric cars. We hope it works — everyone knows we could use more efficient batteries. In the meantime, the first Formula E grand prix is set for this September in Beijing.
