In space, raw honey doesn't flow as it does on Earth. Without gravity pulling it down, it forms floating, sticky blobs that stretch and cling unpredictably.

An astronaut washes his hair in space One of the unexpected challenges of living in space is washing your hair. In the absence of gravity, water doesn’t fall away instead, it forms floating bubbles that stick to your hair. To stay clean aboard the International Space Station, astronauts have to rely on special techniques

Any experiment in space quickly reminds you that gravity does a lot of unpaid work on Earth. Without it, even the simplest tasks turn into puzzles. Here, I was extracting samples from bags of microalgae I had been growing for the past two weeks. The challenge: collecting samples without air bubbles. On Earth, you simply flip the syringe and let gravity usher the bubbles politely to the top. In microgravity, they refuse to cooperate—no rising, no settling, just floating wherever they please. The solution: become the centrifuge. Lacking gravity, I provided my own by spinning, using motion to push the liquid toward the syringe tip and persuade the air to move elsewhere. It took a few tries (and a bit of trial-and-error choreography) before it worked. Multiply that process by twelve bags, four samples each, and several spins per sample, and the math becomes clear. Let’s just say I logged an impressive number of rotations that day—proof that in space, science sometimes looks a lot like interpretive dance. #shux #space #axiom4 #shubhanshushukla #india #iss

SPACE DOESN’T HAVE A TEMPERATURE Out in space, there’s no air to heat up or cool down, so “temperature” doesn’t really work the way it does on Earth. Touch sunlight and you’d fry, hide in the shade and you’d freeze, all in the same spot. Space is basically the ultimate “it depends” answer to how hot or cold it is. Source: CosmicCurios

🚀 This is why you literally CAN’T shower in space. 💦 Astronaut Chris Hadfield wrings out a soaking wet towel on the ISS… The water doesn’t drip. It just forms this wild floating blob. Zero gravity is straight-up insane .😱 Would you survive 6 months without a real shower? Drop your answer 👇

Floating through the space station lab to my sleep pod. Without gravity, tidiness is different (nothing can fall down). Note the ukulele!

Whilst this NASA Astronaut was out floating around in Space maintaining this Satellite - he also made a Tiktok. Turned out WiFi was pretty good - like it is on Earth.

NEW: Artemis II astronaut Christina Koch shares the funny moments she's experienced back on Earth having to get used to living with gravity again: "Every time I've been waking up, or in the first few days, I thought I was floating, I truly thought I was floating." "I put a shirt in the air and it went. *THUD* It actually surprised me."

In contrast Bolin runs toward a lava flow, SHUTS HIS EYES, stops it, pushes it back, cools it down, and says the equivalent of “well that just happened.” No training, nothing. He didn’t even know he could do it, and he does it perfectly, with his eyes shut.

Once you return from space, your body discovers that Earth is no longer as intuitive as it once was. After weeks in microgravity, it has become remarkably efficient at living in an environment where up and down are merely suggestions. Reacquainting it with gravity takes time. Post-flight rehabilitation is a carefully designed program tailored to each astronaut, gradually increasing the intensity and complexity of exercises to retrain balance, coordination, strength, and endurance. The objective is simple: keep challenging the body until Earth feels natural again. At times, I was convinced that my instructor, Emiliano Ventura , had made it his personal mission to find new and creative ways to make me fall. But that is how you learn. By falling. Whether after a space mission or in life. #shux #space #shubhanshushukla #india #axiom4

ISS or a 1980s hairspray commercial? 🤡 These so-called “astronauts” claim to be floating in zero gravity, yet their hair stands stiff as a board. Where’s the natural movement? Why doesn’t it flow freely? It’s almost like… they’re not really in space at all. Wake up! NASA’s been running this scam for decades.

🚨🇺🇸 FIRE IN SPACE LOOKS NOTHING LIKE EARTH - NASA’S ZERO-G FLAME IS A FLOATING GLOW BALL On Earth, fire flickers up because hot air rises and pulls oxygen in from below. But in space? No gravity, no flickering. NASA ran a microgravity experiment and lit a flame inside a sealed chamber - and instead of dancing, the flame puffed into a glowing sphere like a tiny ghost lantern. It doesn’t stretch, doesn’t wave, just floats there burning evenly in all directions. Super chill, super weird. Basically, fire in space is less “campfire vibes” and more “plasma jellyfish with zero chill.” Source: NASA

How did Korra bend earth to that height while firebending at the same time? It was like the earth was floating on its own.

THERE’S NO SUCH THING AS ZERO GRAVITY Astronauts aren’t floating because there’s no gravity. They’re floating because they’re falling... with style. The International Space Station experiences about 90% of Earth’s gravity, but it’s moving so fast, it’s constantly missing the ground. At 17,500 mph, it’s like a cannonball fired so hard it never lands. But make no mistake: if we cut the engines, it will fall. Source: modernday_eratosthenes
