NASA Goddard: NASA’s Guide To Black Hole Safety. (YouTube, 2:39min) “Have you ever thought about visiting a black hole? We sure hope not. However, if you’re absolutely convinced that a black hole is your ideal vacation spot, watch this video before you blast off to learn more about them and (more importantly) how to stay safe.”

Have you ever heard of The Biggest Little Railway in the World? It was
“a temporary 71 mile (114 km) 1.25 inches (32 mm) O-gauge model railway from Fort William to the City of Inverness, the two largest settlements in the Scottish Highlands. It has been described as a crackpot project to run a model train the length of the Great Glen Way by an army of madcap enthusiasts, geeks, and engineers in the best spirit of eccentric Britishness.”
56 volunteers built it over the course of 12 days and also drove the engine called Silver Lady along it. The track included a temporary bridge across the Caledonian Canal, a huge trestle bridge and a spiral loop near the end that enabled the train to climb five metres over a very short distance.
The model train achieved what the real railway didn’t: It ran from Fort Williams to Inverness.
There is a five-part Channel 4 TV series about this incredible project that you can watch in its entirety here:
Futility Closet: Thinking Big. (5 x 45min)
I watched it over the past few days and enjoyed it thoroughly even though I’m neither a train nor model train enthusiast.
World Unicycle Tour is just exactly what it says: Ed Pratt from Somerset, England, cycled around the world on his 36″ unicycle starting on 14th March 2015 and returning home on 27th July 2018, racking up some 22,000 miles. Read more about him and his tour or take a look at his route. For a while, he also kept a blog, the first entry of which is here.
The best bit though is his YouTube channel Ed Pratt Unicycles the World where he posts videos from his trip weekly. I’ve spent the past few days catching up by watching all of his videos, and they are exceptional. A few highlights: Germany, Ed cycled trough the Upper Middle Rhine Valley (I used to live there), How to film camels on a cycle tour, Ed unicycles China (trailer), Ed unicycles Australia (trailer), Taped a GoPro inside my wheel (also check out the second perspective – so weird, but fun!), Ed Unicycles New Zealand (first episode), and the most recent series (ongoing): Ed cycles South East Asia.
I don’t know why this guy only has 32,000 subscribers on YouTube, but I hope he gets a wider audience because his project is laudable – he collects donations for “School in a bag”, and his videos are interesting and well-edited with a fantastic soundtrack.
