Safest thing redbull has ever done..

@ganymede19

1) You're not testing reflexes if you give them a countdown.
2) some people have their hand below the ruler while others are starting at 5 cm

@Liljuanlj

“Yo how fast is your reaction time?”

“12 cm…” 😂

@CDH1986

The most unfair test in the history of unfair tests

@ArtemSolomenko

h=gt^2/2. 
Reaction:
t=(2h/g)^1/2
Centimetr must be converted to meter. And then the reaction will be in seconds.

@jorgejurijiwmut8345

It would be interesting to test it against E-Sports players

@AbeLeon07

When they test with knives, I will agree it's the Redbull.

@flyingtofu8074

F1 driver = ultra instict

@vladimircurkoski1455

I'm not surprised with F1 drivers reactions

@beniocabeleleiraleila5799

8cm means 0.128 seconds reaction time, the formula is:
Square root of (distance/4.9)

How to get the formula:
The ruler start to move at time t=0 with no initial velocity and under influence of the gravity acceleration, it will travel a distance D in T seconds, being T the time of reaction
g/2 * T^2 = D, g is around 9.8, so g/2=4.9

T^2 = D/4.9
T = sqrt( D/4.9 )

@Huggiii

Good thing no one was injured.

@Jovitinha

Good to see David Coulthard's reaction time is still top notch.

@Dasty_777

Кажется, что разница большая, но если знать формулы, можно вывести это:
S=at^2/2
Формула для ускорения, если начальная скорость нулевая. 
Так как линейка имеет очень маленький объем и ее конец маленькую площадь, то силой архимеда и сопротивлением воздуха можно пренебречь. А значит ускорение будет примерно 9.8 м/с^2.
Выведем время из формулы. 
t^2=2S/a
t=√(2S/a) 
Подставим значения
29 см:
t=√(2*0.29/9.8) 
t≈0.243с или же 243мс
9 см:
t=√(2*0.09/9.8) 
t≈0.136 с или же 136мс
243мс и 136мс различаются менее чем в 2 раза, хотя 9см и 29см различаются более чем в 3 раза. 
Так что теперь вы знаете, что в видео реакция гонщиков где-то 130 мс, но в гонке она конечно будет лучше)

@Sxyline

F1 Players have more reflexes than normal people, this is super important for them, or else if they wouldn't have good reflexes alot of things in F1 could go wrong, they have to do alot of exercises.

@skyppi

What is ALKAN doing there😂

@mayurgadhavi1113

True example of how f1 driver are more responsive for any moment to react 🎉

@joshuacress5174

My toxic trait is me thinking i could beat them all easily. 😂

@matphil

Nah these red bull stunts are getting crazier by the day 😳💀💯

@bunk-rl

To do one of these reflexes I recommend that you try to count 3 seconds or less, and at the end of the seconds doing the movement to achieve it does not always work but you are more likely to predict to do it because it does
