How the AK-47 Works — (Simple, Visual Explanation) In this video we break down the legend: the AK-47. Learn the history, the key parts, and the basic operating principle behind the world’s most famous rifle — explained in plain English for beginners. No technical build instructions — just how it works and why it became so reliable. Safety & legality This video is educational. It explains mechanical principles only and does not provide instructions for manufacturing, modifying, or evading regulations. Always follow local laws, and seek certified training if you handle firearms. Want more?

3D animation showing how an AR-15 works.

Here is an animation I did that shows how a bowling alley works. This particular design is taken mostly from Brunswick's pinsetter. The ball return is taken from AMF's Gripper ball lift. Please note that I wasn't going for an exact representation of a particular type of bowling alley. This was just to demonstrate the basic understanding of how it all works. I created the geometry in 3ds max and the animation was done in Cinema 4D. I then used After Effects to compile everything and to add sound effects etc.

Save money and avoid unnecessary engine machining. In many cases blue exhaust smoke, high oil consumption, and blow-by are caused by worn piston rings — not a damaged cylinder. In this video I show the exact tests and signs mechanics should use before recommending a bore: compression test, wet compression test, leak-down test, and borescope inspection. I also walk through the repair path: replacing rings + a light cylinder hone and break-in tips.#EngineRepair #PistonRings #CompressionTest

Beneath the ocean, nuclear submarines are self-contained cities. This documentary explains, in clear, research-based terms, how submarines generate breathable air from seawater, produce fresh water, run compact nuclear reactors for years, and use layered safety systems to avoid meltdowns. We cover: electrochemical oxygen systems and CO₂ scrubbing, desalination from reactor heat, reactor design and control systems, passive safety features, crew life-support routines, and why decades of naval practice have made these vessels remarkably safe. What’s in this video • Oxygen production & CO₂ removal • Fresh water generation and supply systems • How submarine reactors work (compact, pressurized designs) • Cooling, control rods, and fail-safe mechanisms that prevent meltdowns • Life aboard: routines, psychology, and logistics #NuclearSubmarine #Engineering #Documentary #NavalHistory #LifeSupport

Uranium sits at the heart of two very different technologies: peaceful reactors that supply steady electricity, and weapons that release energy in milliseconds. This video explains the science, engineering, and policy that make reactors useful for power — not bombs — and why uranium became the backbone of nuclear energy. What you’ll learn (bullet list): How nuclear fission produces heat and why control (not the element) determines the outcome. Why most power reactors use low-enriched uranium and how that enables safe, steady operation. The conceptual differences between reactor design and weapon design (non-actionable, high-level). Plutonium’s role as a reactor byproduct and the safeguards that matter for peaceful programs. Myths vs reality: separating fear from facts about nuclear power.
