The world’s largest horn isn’t just ridiculously huge — it’s powerful enough to make glass shatter. Mark Rober builds an enormous air horn and uses it to demonstrate just how dramatically the shape and size…
Japan’s 400 km tsunami seawall is a coastal engineering project on a scale that’s difficult to comprehend. Stretching along hundreds of kilometers of Japan’s northeastern coastline, this enormous network of defenses emerged from the rebuilding…
The world’s largest elephant toothpaste experiment takes a classic science demonstration and scales it up to an absolutely ridiculous level. Instead of a little foam spilling from a bottle, Mark Rober and Science Bob set…
The fastest man-made objects operate on such wildly different scales that numbers alone struggle to make their speeds feel real. Put them together in one 3D comparison, however, and even seriously fast cars suddenly begin…
A red-hot metal ball experiment becomes strangely irresistible when the glowing sphere meets objects that were never designed to handle extreme heat. Coconut, rubber bands, matchsticks and other everyday materials are all put to the…
Building a suspension bridge is already a massive engineering challenge. Building one high above rugged terrain, with enormous towers, cables and sections of roadway seemingly suspended in midair, takes that challenge to an entirely different…
A Coca-Cola can looks like a simple piece of aluminum, but there’s something hiding inside it that most people never notice. This short experiment reveals the nearly invisible layer separating the drink from the metal.…
A spinning CD looks perfectly solid — right up until rotational forces become too much for it to handle. But when that destruction is filmed at an astonishing 170,000 frames per second, the split-second explosion…
You already know how to ride a bicycle. So if someone simply explained one tiny change to the steering, surely you could adapt almost immediately… right? That’s what engineer Destin Sandlin thought before trying a…
Optical illusions are always interesting for the viewer especially when you’re trying to find out the reality behind them. The way your eyes perceive from an object sometimes differs from the way it is interpreted…
