This laser can't escape the water. Physics won't let it. It's called total internal reflection and it's the same physics behind fiber optic cables.

Well, some light is still escaping, otherwise we wouldn't see that red glow! 😉

It’s crazy to think this exact physics concept is what delivers high-speed fiber optic internet straight to our homes!

You see it, so it's already escaped.

Science just casually doing magic tricks ✨ This is total internal reflection. Same physics that runs the entire internet through fiber optics.

If it can’t escape then why can I see it? 🧐 some portion of light doesn’t escape but looks like a fair portion does.

Key properties of laser light: monochromatic, coherent, and directional. While the principle of stimulated emission was theorized by Einstein in 1917, the laser was first invented in 1960, and became popularized by the film Goldfinger in 1964, where laser metal-cutting was not even possible until 1967.

Not necessarily 100% true...you can still see photons escaping because the coefficient of reflectivity inside the stream is not 100%... Otheriwse, you'd see only the reflectance of the room on the outside of the water stream and no red laser light...

Only really viable with laminar flow though. Must have homogonous surface tension uniform enough to not lose the light to scattering disruptions in the water molocules. Many years ago, I did this with a green laser and a massive laminar jet I made from scratch that shot 30ft into the air. The laser followed it all the way back to the ground. Very cool and fun to see a bendy water laser lol.

When light inside water hits the surface at a steep enough angle, it stops escaping and reflects completely back into the water. It’s called total internal reflection, and it’s a reminder that even light doesn’t always travel the path we expect.

This mesmerizing fountain demonstrates a beautiful combination of laminar flow and total internal reflection, transforming an ordinary stream of water into a living fiber-optic cable Unlike a typical fountain, a laminar nozzle produces an exceptionally smooth, glass-like stream by forcing water to flow in parallel layers with minimal turbulence. The result is a crystal-clear arc that remains remarkably stable as it travels through the air

Elon’s entire engineering philosophy in one sentence: “Physics is the law, and everything else is a recommendation” "Physics is a harsh judge, and there's no fooling physics. If something's wrong, the rocket's going to explode. It's not going to get to orbit. So it's not like, "Elon, you're amazing," meanwhile the rockets are blowing up. It's hard to say you're really kicking ass here when the rockets are exploding.....that's just not the case Generally, the rockets need to get to orbit, the satellites need to work, the Starlink connection needs to work, or bad things happen. This is sort of a physics situation, and physics is a harsh judge. I say physics is the law, and everything else is a recommendation. I've seen people break the laws made by humans, but I've not seen anyone break the laws made by physics. And rockets are ruled by physics"

"He's so shy and so humble, he was at a GDC talk about Angry Birds physics and just went up and said 'yeah, I wrote that physics engine.'" Also: the Overwatch netcode engineer built their custom networking. This tiny team is stacked.

$n₁ sin θ₁ = n₂ sin θ₂ Watch this laser hit the glass-air boundary. At first, it bends out (refraction). Then... boom. Angle exceeds the critical θ_c = arcsin(n₂/n₁) ≈ 42° for glass (n≈1.5), and every photon turns back inside. No leakage. Pure total internal reflection. This is why fiber optics carry the internet across oceans without losing signal. Why diamonds sparkle like crazy. Why light can get trapped in a stream of water.$

China has raised prices of fiber optic cables, which are critical for drone control, by 2.5-4 times for Russian buyers, according to Russian media. At the beginning of 2025, G.652D fiber, used in telecommunications cables, cost 16 yuan ($2.33) per kilometer in China, and in January 2026, it already cost 40 yuan ($5.80) per km. In 2025, Russia purchased 10.5% of all fiber optics produced worldwide, although in previous years this figure never exceeded 1%. In absolute terms, Moscow purchased 60 million km of fiber optic cable last year. At present, Russia does not have its own fiber optic production, and the only enterprise, Optical Fiber Systems in Saransk, was shut down after a series of drone attacks in April-May 2025. 📹: A web of fiber optic cables from drones in the forests of the Kharkiv region
