With the frictional properties of a metal gauntlet, they imagined it might be impossible.

After collecting them all, he snaps his fingers and triggers universe-wide consequences.īut would it be possible to snap at all while wearing an armor gauntlet, the researchers asked? In the case of a finger snap, they suspected that skin friction played a more important role compared to other spring and latch systems. In it, Thanos, a villainous character, seeks to obtain six special stones and place them into his metal gauntlet.

It posits that organisms depend on the use of a spring and latching mechanism to store up energy, which they can then quickly release.Īcharya and Bhamla felt a particular push to apply this framework to a finger snap after seeing the movie Avengers: Infinity War, released in April 2018 and produced by Marvel Studios. The framework seemed to naturally apply to the snap. In earlier work, Bhamla, Ilton, and other colleagues had developed a general framework for explaining the surprisingly powerful and ultrafast motions observed in living organisms. "It's really an extraordinary physics puzzle right at our fingertips that hasn't been investigated closely." "For the past few years, I've been fascinated with how we can snap our fingers," Bhamla said. Bhamla said the project is also a prime example of what he calls curiosity-driven science, where everyday occurrences and biological behaviors can serve as data sources for new discoveries. Their results might one day inform the design of prosthetics meant to imitate the wide-ranging capabilities of the human hand. The research was led by an undergraduate student at Georgia Tech, Raghav Acharya, as well as doctoral student Elio Challita, Assistant Professor Saad Bhamla of the School of Chemical and Biomolecular Engineering, and Assistant Professor Mark Ilton of Harvey Mudd College in Claremont, California.

In this round of physics vs supervillains, physics came out on top.Using an intermediate amount of friction, not too high and not too low, a snap of the finger produces the highest rotational accelerations observed in humans, even faster than the arm of a professional baseball pitcher. The metal armor would have not provided enough friction or compressibility, resulting in sluggish snaps. So the verdict on Thanos’ snap? The team tested the power and speed of the finger snap wearing thimbles, though the results fell short.

The forces behind the highspeed event may be able to be applied to high-tech prosthetic hands, creating more realistic and free flowing movements. “This is the only scientific project in my lab in which we could snap our fingers and get data.” Understanding this mechanism isn’t just interesting, but also important for biomechanics. “Based on ancient Greek art from 300 B.C., humans may very well have been snapping their fingers for hundreds of thousands of years before that, yet we are only now beginning to scientifically study it,” said Bhamla. The report, published in the Journal of the Royal Society Interface, showed the impressive seven millisecond time period of the snap – around 20 times as fast as a blink of the eye! The finger also accelerates at a rate of 1.6 million degrees per millisecond, three times the amount of a professional baseball player’s arm when pitching. When adding lubrication into the equation, the snap fell short, emphasizing friction as a key parameter also.
“This is how this whole thing got started because we want to figure out the key ingredients required to snap our fingers.”Īfter recording the event, the results showed that the finger pads ability to compress is a key factor behind it. “We got into this heated debate, trying to understand if he could actually snap or not,” Bhamla said. They wanted to investigate if a snap in such a rigid glove would even be possible. Thanos, the evil villain in the story, uses his superpower snap whilst wearing a metal glove to wipe out half of the universe. The research group, led by Saad Bhamla, actually took inspiration from Marvel’s 2018 smash hit Avengers: Infinity War. Thanks to high-speed video footage from Georgia Tech in Atlanta, exactly how impressive the movement is has been exposed. Turns out the simple snap is a physics gold mine.
