“_If you touch the👇black point then your whatsapp will hang_”, says the message that’s being sent around, and it’s right. It’s a text rendering bug, the same as many others — which isn’t interesting. But the characters it’s using, Unicode RTL and LTR marks, are worth knowing about.

The devil’s kettle waterfall is believed by some to be a gateway to another universe or even to hell itself. The two streamed waterfall has baffled geologists for decades as no one can work out where the water flowing into the kettle leads. It’s as if it simply disappears. But that’s not the only mysterious water structure. In the amazon river is now known to be a boiling river hot enough to kill any creature to fall into it. It was thought nothing more than a myth until it’s recent discovery and no one knows why the water is hot enough to boil.
In India stands a small village known for having a high twin rate. It’s obvious why the settlement is now known as twin town but less obvious why so many twins are born here. Suggested answers include the claim that government experiments secretly changed the genetics of locals decades ago.
Perhaps the most mysterious location is the zone of silence in Mexico, a place known for magnetic phenomena and as a dead zone for radio. You will receive no radio signal while in the zone and don’t expect your compass to be reliable. Also watch out for mutated animals or strange alien like figures – those are never a good sign.

G-Force, Jerk, and Passing Out In A Centrifuge
Thanks to the Starrship team for arranging this! I’m also over on their channel, flying with the Blades: https://www.youtube.com/watch?v=iWY3-1gOrxk • At the Royal Air Force training centrifuge in Farnbrough, pilots learn how to avoid G-LOC: g-induced loss of consciousness. Let’s talk about g-force, about jerk, and about how to keep circulation flowing to your brain.
* Isn’t 3.6g a really low g-tolerance? *
* What g was the RAF person at the start pulling? *
* Why did you shake and shudder when regaining consciousness? *
* What did it feel like? *
* Is this a sponsored video? *

Not Everyone Should Code
First 500 people will get 2 months of Skillshare free: https://skl.sh/polymatter4
It’s become popular to encourage anyone and everyone to code. But there simply won’t be unlimited demand for the skill, nor will everyone actually enjoy it.

Making Artificial Earthquakes with a Four-Tonne Steel Ball
In Gottingen, Germany, there’s a four-tonne steel ball that can be raised up a 14-metre tower — and then dropped in less than two seconds, crashing back to earth. It makes tiny, artificial earthquakes: here’s why.
Thanks to all the team at Wiechert’sche Erdbebenwarte Gottingen! You can find out more about them here: https://www.erdbebenwarte.de/
Three things I had to cut out of this video, because they didn’t quite fit into the story or because I couldn’t film them:
The reason the steel ball survived two world wars is because the university’s records listed it by use as a “rock-ball”, not by composition as a “steel ball” – so no-one melted it down for weaponry.
The observatory team refill that pit every year to make the ground flat, and the ball just digs a hole again. The rock’s just being compressed underneath. They joke that, somewhere in Australia, there’s a slowly growing hill…
And finally, the ground steams for a little while after the ball hits: it gets rather warm…
