Wild fact: the earth has had the same water for 4 billion years. It’s all recycled. The water you drink today could actually be from the iceberg that hit the Titanic... or it could have once been someone else's toilet water #science #learnontiktok #wastewater #howitworks #cleaning

Most people picture 911 operators pushing a button and your dot popping up on a map. The reality is your phone is doing the work, timing signals from satellites, reading nearby WiFi, and even sensing air pressure to see which floor you’re on. #learnontiktok #howitworks #techtok #911 #gps

You've probably heard about "toxic black mold." It's real, and worth taking seriously, but it's also widely misunderstood. On the wall it looks greenish-black and slimy, then dark and powdery once it dries. Here's what it actually is and why it shows up. (Curious about the black stuff in your shower? I made a longer version of this video for YouTube, link in my LinkTree) #cleantok #science #mold #learnontiktok #biology

Every photo you upload lives in a real building somewhere. Your data gets copied across multiple drives and is given an address so it can be found again whenever you or someone else pulls it up. And what’s so crazy is that this all happens in a fraction of a second. Doing this constantly for everyone online at the same time takes a ton of computing power. This is data centers explained in 3 minutes! #learnontiktok #datacenter #infrastructure #computerscience #techtok

Some cities survive almost entirely by drinking ocean water. In the desalination process, we push seawater through a salt-blocking membrane until only fresh, drinkable water comes out the other side. #science #physics #desalination #water #ocean

Your brain has its own cleaning system and it was only just discovered in 2012. While you sleep, cerebrospinal fluid flows through your brain tissue, picking up toxic waste proteins and draining them out. Here’s how it works and how you can boost your glymphatic system. #science #neuroscience #brain #sleep #brainfog

Brake pads have one job, and it's to wear out. They’re sacrificial by design. Every time you press the brake pedal, microscopic pieces of the pad flake off so the rotor stays intact. The pads are made of kevlar, ceramic, copper, and even cashew shells. The squealing sound? Intentional. The dust? Worse than diesel exhaust. The most underappreciated engineering on your car. #brakes #engineering #tiktoklearningcampaign #physics #cars

The U.S. has 94 active nuclear reactors that help power our cities. But do you know how they actually work? Most of them are pressurized water reactors (PWR), and the process is simpler than you might expect. #nuclear #science #stem #tiktoklearningcampaign #LearnOnTikTok

Ever wonder why roads are black? It’s not tar, it’s not oil, it’s actually a substance called bitumen and is the leftover reside at the bottom of the barrel after crude oil gets refined. #learnontiktok #science #asphalt #tiktoklearningcampaign #physics

How does mixing four simple ingredients create concrete? And why do we use billions of tons of it a year? #science #physics #howitsmade #concrete #learnontiktok

How do we turn sand into glass? And is there really a sand crisis? #science #glass #physics #howitsmade #explained

Why do we have earthquakes? They’re not random. #physics #geology #popularscience #earthquake #learnontiktok

Hydropower converts 90% of falling water's energy into electricity. No fuel, no emissions, just gravity. Here’s how hydroelectric dams work. #physics #science #infrastructure #learnontiktok #howitworks

There are over 12,000 nuclear warheads in the world across 9 countries. Here’s how they work. #howitworks #science #physics #learnontiktok #nuclear

We make two billion tons of steel every year. It's the only material that can be recycled indefinitely. But iron ore is finite, and reserves won’t last forever. #sciencefacts #howitsmade #engineering #steel #construction

In the 80s, scientists discovered we were destroying the one thing protecting us from the sun’s deadliest radiation. Here’s how we saved the ozone layer. #science #learnontiktok #environment #space #stem

Nuclear fusion, explained. It could solve our energy problems forever. (This is not to be confused with fission, that’s in my other nuclear video!) #learnontiktok #howitworks #stemtok #fusion #physics

Nuclear reactors, explained. They’re basically just a really intense way to heat water and turn that into energy. #howitworks #learnontiktok #sciencetok #nuclear #physics
