Scientists engineered “unsinkable” metal tubes by making ordinary metal superhydrophobic—so water can’t penetrate even when punctured or submerged.

Inspired by diving bell spiders & fire ant rafts, researchers built a laser-etched metal that traps air and won’t sink—even when punctured. Unsinkable ships, resilient flotation gear, and long-life ocean sensors? Nature-inspired physics says it’s possible. It’s 6 years old…

It’s hard to accept the sky is being sprayed with metal particulates each day, it’s even harder to accept that these metal compounds are then manipulated by frequency. Sadly, you can see both happening in real time everywhere, therefore making it a reality that some people will accept and some people won’t. However both points are simply undeniable.

After Metal Slug 2, the reason X came out before 3 was because Metal Slug 2 had serious optimization issues, causing heavy slowdown during gameplay. So SNK decided to release an optimized version based on Metal Slug 2 first. That said, it wasn’t exactly the same game. They changed things like switching between daytime and nighttime backgrounds to create a different atmosphere, and even brought in some weapons that would later appear in Metal Slug 3. The controls were also improved, showing that a lot of care went into refining the experience. When you actually play it, you can clearly feel that the slowdown is significantly reduced compared to Metal Slug 2. Because of that, Metal Slug X became a very popular title alongside Metal Slug 3.

Between binders and liver support, I can’t explain it, but my cardiovascular endurance has improved so much. Idk if it’s an endotoxin thing, or a heavy metal thing, but getting into shape for a fight is so much easier. Rebounding from training extremely fast.

re- post: Living metal! Frequencies change and control the metal that these craft… SPHERES ARE MADE OF. This is how they combine together to make larger ones… or how they birth smaller ones… Or when the Hellfire Missle hit the one by Yemen and it birthed 3 smaller ones in defense. Now… you see for yourself!! This my friends has only been witnessed by Military Personnel!!! Check it out!! Jon Stewart Patrick Jackson

In Inglourious Basterds (2009) the burning cinema scene gets even wilder when you know the giant swastika wasn’t meant to collapse. The flames burned so hot the metal supports actually melted on set & Tarantino kept it in.

So basically they were right...when they said, Partners look similar or same 😬 I can’t even spot the difference 😭

Franck Zanu on White People: “They can command water from far away through tubes into their bedroom, we can’t even fetch a bucket of water from the next lake.” “They used to have a joke in Ghana that when God said let’s pray, the white man opens his eyes and the black people were covering their eyes so the white man saw how God created the world that’s why they are so good at what they do.”

so i thought metal gear solid was a realistic game series where the most ludicrous or "unrealistic" thing that happened is more nukes and quicker heal times so imagine my reaction when learning that this game apparently isn't as realistic as i thought

Printing metal made easy! 🖊️ Most metal 3D printing today relies on heat. Lasers or electron beams melt metal powder or wire, fuse it, and let it solidify again. That works, but it’s inefficient: a lot of energy is lost before it ever reaches the material, and even more is wasted as heat dissipates into the surroundings. This work explores a very different idea. Instead of melting metal, it uses high-frequency, low-amplitude mechanical vibrations to temporarily lower a metal’s yield stress and enhance atomic diffusion. Under these conditions, metal can be shaped and joined without full melting. By combining shaping and joining at the same time, the researchers introduce a new additive manufacturing process called Resonance-Assisted Deposition (RAD). Because it avoids melt–solidification, RAD is far more energy-efficient and enables things that are difficult or impossible with conventional methods. Pretty cool method!

Have you ever heard of EDM (electrical discharge machining)? 🤔 Watch as these metal parts get cut with a hair-thin copper wire and a high-frequency pulse generator with temperatures reaching tens of thousands of degrees… The metal is cut within a deionized solution to keep it cool while cutting. When they lower the pieces back together, they slide perfectly into each other with literally ZERO gap or visible cut marks! No material is lost like normal cutting, so the parts fit like they were never separated. How is this even real?! 👇

What a grim mess. When pressed by Stephen Flynn MP, this Labour minister can’t even confirm whether Mandelson has had the whip removed or not 🥀
