The World’s Fastest Roller Coaster Travels Nearly 150 mph

On November 4, 2010, Formula Rossa, the world’s fastest roller coaster, opened in Abu Dhabi’s Ferrari World—the first Ferrari-themed amusement park in the world to be dedicated to the Italian sports car. The steel coaster hits 4.8 Gs (for context, NASA astronauts experienced up to 3Gs during launch in the space shuttle), stands at 170.6 feet (52 meters), and stretches to 1.4 miles in length.

Once launched, Formula Rossa goes from 0 to 149 mph—the top speed—in 4.9 seconds. It’s so fast that riders must wear safety goggles during the one-minute long ride.

Formula Rossa is what’s known as a launched coaster; it uses a hydraulic launch method similar to an aircraft carrier. According to ESFStream.com, “Engineers had to develop and produce its motors, pistons, and pumps in every train to pump the speed up by a lot. There is a deflecting roller on the bottom of the train inside the train track that gives the train better curve control at extreme speed.”

The coaster car itself looks like a red Ferrari Formula 1 vehicle, and in 2014, actual Formula One drivers Kimi Raikkonen and Fernando Alonso tested the coaster. While Alonso seemed to enjoy it, the Daily Mail reported Raikkonen appeared bored.

Though Formula Rossa has held the world’s fastest title for almost a decade, it faces stiff competition. In 2023, Six Flags plans to open an amusement park in Saudi Arabia, and if all goes well, its coaster, Falcon’s Flight will not only be the “world’s most extreme roller coaster in the world” but also the world's longest, tallest, and fastest roller coaster ride.

This 1000-Piece Jigsaw Puzzle Honors 11 Unforgettable Women Who Made History

Galison/Amazon

The assertion that “well-behaved women seldom make history” has been an oft-quoted feminist slogan ever since historian Laurel Thatcher Ulrich first wrote it in the 1970s. This 1000-piece jigsaw puzzle from Galison ($18) honors women from all eras who truly embody the phrase.

The image, illustrated by creative designer Ana San José, depicts a woman walking through a portrait gallery, gazing up at gilt-framed paintings of 11 icons who have pushed the envelope on what society thinks women can (or should) do. Some, like Amelia Earhart and Jane Austen, are household names, while others haven’t been as well-represented in education and popular culture. Japanese mountaineer Junko Tabei, for example, became the first woman to reach the top of Mount Everest in 1975; and NASA mathematician Katherine Johnson was instrumental in sending astronauts to the Moon. The puzzle includes a living legend, too: Malala Yousafzai, Pakistani education activist and the youngest Nobel Peace Prize laureate in history.

The completed puzzle measures 27 inches by 20 inches and comes with a printout showing the full image, which you can use as a guide. The pieces are printed with no-glare ink, so you won’t have to constantly reposition yourself (or the pieces) to keep your light source from obscuring your view. And when you’re finished, you can either pack the puzzle back into its box, or seal it with puzzle glue ($13) and hang it on a wall to create your very own mini feminist portrait gallery.

You can purchase the puzzle for $18 from Amazon.
