SAEDNEWS: The Fascinating World of Weightlessness: A Fidget Spinner in the Hands of ISS Astronauts Reveals the Magic of Physics
According to the Science and Technology section of the Saed News website, a recently circulated video shows an astronaut aboard the International Space Station spinning a simple fidget spinner in a microgravity (weightless) environment.
On Earth, this device typically spins for only a few seconds before slowing down due to air resistance and gravity. However, in space, where there is no direct gravitational pull and virtually no air friction, it behaves in a completely different and striking way. The spinner floats gently within the cabin while rotating, and the entire object also drifts and turns through the air at the same time, creating a surreal and visually captivating scene.
Beyond its entertainment value, this simple experiment effectively illustrates Newton’s laws of physics, particularly the first law (inertia). Astronauts use such demonstrations to show how objects without a supporting force can continue moving for extended periods. Interestingly, even the spinner’s center of mass shifts while it is suspended, causing the entire structure to behave somewhat like a small satellite inside the space station.
These brief yet meaningful moments highlight how physics operates differently beyond Earth’s atmosphere, creating a fascinating and unusual environment that continues to captivate audiences on the ground.
