“Study” reveals that finger crackling is the fastest movement in the human body Video

A new study has discovered a very fast movement in humans, which almost everyone does without even realizing for a moment, that it is one of the fastest movements of the body and exceeds the speed of the eye blink.

A team of scientists and researchers at the Georgia Institute of Technology measured the speed and acceleration of the crackling of the fingers, which is located between the thumb and middle finger.
The scientists used high-speed cameras and the latest force sensors to measure.

Scientists have found that this finger crack is the fastest movement in the human body ever recorded, according to the Scientific Journal of the Royal Society Interface.

The results showed that the speed of the finger during this movement reaches 7800 degrees per second and that the maximum acceleration of rotation is 1.6 million degrees per square second, a speed more than three times the speed of the arm of a professional baseball player, according to what the magazine “livescience” reported.

The clicks act by using the arm muscles as a motor to load the spring-like tendons in the fingers and arms that provide them with flexible potential energy, which is quickly released to generate the amazing acceleration of the fingers.

The friction between the thumb and middle finger plays the vital role of the latch by attaching the middle finger to the thumb and preventing it from moving. Once enough energy is created, the friction is overcome and the thumb and middle finger release from each other, unleashing the collision that produces the sound.

“When I first saw the data, I jumped out of my seat,” Saad Bhamla, associate professor of chemical and biomolecular engineering at Georgia Institute of Technology, said in a statement. “The flicker of a finger occurs in just seven milliseconds. It’s 20 times faster than the blink of an eye.” which takes more than 150 milliseconds.”
