If you’ve been a subscriber for a while, you probably know where this one is going. Although you may still be surprised about where I ended up going… Montana’s Giant Springs State Park, and Lake Sumiainen in Finland, have very short rivers. Finding the shortest in the world, though: that could be trickier. Sources: https://www.cntraveler.com/stories/2012-06-18/d-river-lincoln-city-oregon-ken-jennings-maphead

The Berkeley Pit, in Butte, Montana, was once the richest hill on Earth: the Anaconda Copper Mine. Now: it’s not all that rich, and it’s not much of a hill. Instead, it’s a toxic pit filled with sulfuric acid.

http://tomscott.com – http://twitter.com/tomscott – In north-west Germany sits Bielefeld, a city complete with castle, cathedral and citizens. Just one catch: according to something that’s half urban legend, half in-joke, it doesn’t exist. Let’s talk about belief and Bielefeld.

http://tomscott.com – http://twitter.com/tomscott – In a fjord near Stavanger, in southern Norway, is Preikestolen: Pulpit Rock. It’s known as one of the world’s scariest tourist attractions, for good reason — but despite the millions that visit it, it’s pretty safe. At least, for current human values of safe. Let’s talk about risk, immortality, and what

A decade ago, engineers found the Humber Bridge had the same problem as many of the world’s suspension bridges: unexpectedly fast corrosion. Here’s how they fixed it, and how they’re checking that it’s staying fixed. Thanks to all the team at the Humber Bridge board, at Cleveland Bridge, and Visit Hull and East Yorkshire, all

If you believe the hype, then the Metropolitan Area Underground Discharge Channel stops Tokyo flooding. It doesn’t. But it is one colossal part of a huge network of flood defences that protect a city that would otherwise be… well, very wet.

Olds Engineering, a traditional workshop and foundry, sits in Maryborough, Australia. It’s not the sort of place you’d expect to find a new industrial invention in the 21st century: and yet the Olds Elevator, patented by Peter Olds, is just that.

http://tomscott.com – http://twitter.com/tomscott – Under the Elbe river in Hamburg, Germany, lies the Old Elbe Tunnel in St Pauli. Like early 20th century tunnels around the world, it has lifts or stairs to take you down and under the river. But this is on a whole different scale to those you might have seen elsewhere…

Baldwin Street in Dunedin, New Zealand, has the Guinness World Record for “steepest paved road over a continuous distance of more than ten metres”. Which is enough to bring in quite a few tourists. What’s the history? And what counts as “steepest street”? Thanks to Mayor Dave Cull and to Gary Blackman. You can see

If you invent a new theme park or amusement ride, how do you test it to make sure it’s safe? There’s no Federal Bureau of Zip Lines. I visited one of the companies that does just that sort of testing – and, now, inventing.

http://tomscott.com – http://twitter.com/tomscott – On the winter solstice, I trekked out to a cold and muddy Avebury Henge, out in Wiltshire, to talk about two things: first, the peculiar and mostly-British belief of ley lines, and second, the fact that it’s basically a hipster version of Stonehenge: bigger, cooler, and you’ve probably never heard of

It’s an incredible piece of Soviet engineering, capable of sending radar pulses so powerful they could see over the horizon. Which, when you

Mount Taranaki, on the North Island of New Zealand, is a large-scale circle that’s visible from space: a stratovolcano with six miles of forest around it. But that didn’t happen naturally. Oh, and there’s a good chance that, in the next fifty years or so, it might explode. GOOD VIDEOS ON NATURAL PERSONHOOD: Law professor

http://tomscott.com – http://twitter.com/tomscott – The Delta Works, to the west of the Netherlands, are one of the modern wonders of the world. But there’s other, lesser-known infrastructure there too: including the Rozenburg Wind Wall, on the Caland Canal, which turns a dangerous, windy stretch of canal into a much more navigable bit of water. It’s

Los Angeles needed water, and lots of it. It still does. And that water comes from the LA Aqueduct, masterplanned by William Mulholland. The end of his career, though, wasn’t such a triumph. This is the story of the St Francis Dam, and the collapse that stopped Los Angeles from taking over an entire valley.

Kerosene Creek is a natural hot spring near Rotorua, on the North Island of New Zealand. And there have been official warnings for years: don’t put your head under water. It turns out that “brain-eating amoebas”, naegleria fowleri, are a real, if rare, thing. Thank you to Associate Professor Siouxsie Wiles! Here are some of

The Ports of Auckland are automating their straddle carriers, which might not seem like much: until you phrase it as “hundred-tonne autonomous robots guided by nanosecond-precision tracking”.

In Sanlúcar de Guadiana, in Spain, there’s a zip line called Límite Zero: the only cross-border zip wire in the world, landing in Alcoutim, Portugal. You land about an hour before you set off. It seemed like a good time to talk about programming. Thanks to all the team at Limite Zero! Tickets and info:
