World’s Fastest

1World's Fastest Car: 431 km/h (268 mph)

Currently the world's fastest street-legal production car (as opposed to concept cars or modified cars) is the Bugatti Veyron Super Sport which can reach a speed of 431 km/h (268 mph).

While only 5 of the World Record model were made out of a total of 30 Super Sports, the other 25 Super Sports will all also achieve this speed with the limiter turned off. After a review by a panel of experts, Guinness considers this not to be a modification, and thus it is eligible for the record.

2World's Fastest Man: 41.38 km/h (25.71 mph)

On May 17th, 2009, Usain Bolt ran the last 100m of a 150m race in just 8.70 seconds, the fastest ever recorded time for a human being over a 100m distance. This equals an average speed of 41.38 km/h (25.71 mph). This is not an official world record as the IAAF – the International Athletics governing body – does not recognize the distance. However, later that August, Bolt achieved the official world record for 100m when he clocked in at 9.58 seconds.

3World's Fastest Computer: 33.86 quadrillions of calculations per second

In November 2014, the "Tianhe-2," a supercomputer developed by China's National University of Defense Technology, retained its position as the world's fastest supercomputer for the fourth consecutive time with a performance of 33.86 petaflop/s (quadrillions of calculations per second) on the Linpack benchmark.

The supercomputer is currently located at the Sun Yat-sen University, Guangzhou, China, and it was developed by a team of 1,300 scientists and engineers.

4World's Fastest Train: 581 km/h (361 mph)

Developed by the Central Japan Railway Company (JR Central) and Kawasaki Heavy Industries, the fastest train in the world achieved a record speed of 581 km/h (361 mph) on December 2nd, 2003.

The experimental Maglev MLX01 train uses magnetic levitation to carry vehicles with magnets, rather than with wheels, axles and bearings.

5World's Fastest Land Animal: 120 km/h (75 mph)

Inhabiting most of Africa and parts of Iran, the cheetah can run faster than any other land animal: as fast as 120 km/h (75 mph) in short bursts covering distances up to 500 m (1,600 ft), and has the ability to accelerate from 0 to 100 km/h (62 mph) in three seconds.

Cheetahs can accelerate four times as fast as a human, thanks to greater muscle power, and can slow down by 14 kilometers per hour in one stride.

6World's Fastest Ambulance: 300 km/h (185mph)

Dubbed the "fastest ambulance on earth," Dubai's newest ambulance is a refitted Lotus Evora that takes paramedics to their intended destinations at speeds of up to 300km/h (185mph).

A defibrillator and first aid kit squeeze in behind the driver's seat, with an oxygen supply in the boot. Inside the two-seater, just above a small control box for the siren and flashing light, a hard-cased widescreen notebook transmits information that the paramedics will gather about the patient back to the hospital, or to an incoming crew.

Dubai's 50 paramedics will have to take driving lessons before using the $160,000 (US) cars, to help them navigate the country's terrible traffic.

7World's Fastest Accelerating Living Thing: A Fungus

The fastest accelerating living thing on the planet can be found in one of the most unlikely places: horse manure.

While the cheetah runs up to 120 km/h (75 mph) and the sailfish can escape predators in the sea by traveling at 109 km/h (68 mph), they are still no match for "Pilobolus crystallinus", also known as the "Dung Cannon fungus."

The pilobolus can accelerate over 70 km/h (45 mph) within the first MILLIMETER of their flight. They go from 0 to 20 km/h in just 2 millionths of a second and pull 20,000 G.

Why does a fungus that lives in poo need to be the speediest thing on the planet? For the fungal family to survive, their spores need to get eaten by another grass eater. To do that, they need to get away from the area around the poo, known as the zone of repugnance (apt name), and that means they must clear over two meters. However, the smaller you are, relatively speaking, the thicker the air becomes. The only solution therefore is to go so fast you can power through the air to get to the fresh grass beyond.

8World's Fastest Temperature Change: a 49 °F (27 °C) rise in two minutes

It was caused by the "Chinook winds," a weather phenomenon of the area.

On January 22, 1943 at about 7:30 a.m., the city of Spearfish, South Dakota had a temperature of -4°F (-20°C). However, the wind picked up speed rapidly and two minutes later, at 7:32 a.m., the temperature was +45 °F (+7 °C) above zero, making it the world's fastest temperature change ever recorded on earth: a 49 °F (27 °C) rise in just two minutes!

By 9:00 a.m., the temperature had risen to up to 54 °F (12 °C), then suddenly, the wind died and the temperature tumbled back to -4 °F (-20 °C). This 58 °F (32 °C) drop took only 27 minutes.

9World's Fastest Rapper: 14.1 syllables per second

In January 2005, rapper NoClue won the title of the world's Fastest Rap MC by Guinness World Records, for rapping 723 syllables in 51.27 seconds (14.1 syllables per second) on his track "New West."

The attempt was recorded at Seattle's B&G Studios on January 15, 2005 in front of a licensed speech therapist.

10World's Fastest Water Slide: 105 km/h (65mph)

Located in Fortaleza, Brazil, the "Insano" is the highest water slide in the world at 41 meters high, as listed in the Guinness Book of Records. Equivalent in height to a 14-story building, the ride plunges swimmers from sky to pool in just four or five seconds, while traveling at approximately 65 miles an hour.

The Brazilian water park website describes the Insano as the most extreme equipment of this type of the planet. At the end of the descent the slide levels off and deposits riders safely in a swimming pool to relax.
