A toxic lake and a baby albatross. (Not at the same time.)

• First up, a diorama of "the well that never runs dry", by Thalasso hobbyer. Miniature work; resin pouring; lighting work; and, of course, the skills necessary to edit it into a 26-minute, silent compilation, with occasional subtitles to explain the process. Put this on as 'slow TV'; it's incredible. (Thanks Jade!)
   
• The bar being raised in a different genre, that of the 'interesting travel story', the genre that I used to be part of. Last time I linked to the channel What On Earth Is This, its host, Gabriel, was making short videos about occasional interesting things, with a few jokes put in. But "if this dam fails, it pollutes half of Europe" (strong language) is 24 minutes of really well-executed video that flies by. I was going to say that this channel deserves to take off far, far faster than it has, and that it's ridiculous that there are so few views on this... but, as with makers, the standards of making things like this are so high now. (Thanks Lennart!)
   
• The team at HowNOT2 set up the longest highline in the world (occasional strong language). The rope is an incredible four kilometres long... and after setting it up, they try to walk over it, high above the Utah desert. I didn't realise quite how far the world record has stretched in the last few years -- and this is a deep-dive into the skills and technology involved to make it work. (Thanks Carl!)
   

• "list animals until failure": a game that seems, initially, both simple and frustrating, because most people's brains aren't indexed in a way that lets them recall every animal. There are, after all, a lot of animals. As you play on, though, you'll find the game's creator thought of a lot of little easter eggs to add. Like, a lot. One of the joys of a Proper Web Game like this is that, if you want a less stressful version, you can tweak the settings to give you as much time as you want. And if you want spoilers for the easter eggs, you can just hit view source -- at least on desktop -- and read the code. I'd recommend playing it at least once first, though! (Thanks Anusha!)
   
• Science articles that make you think "huh, yeah, that's obvious in hindsight": antibodies harvested from the blood of paediatricians are up to 25 times better at protecting against RSV.
   
• Topsy-Turvy World: a series of tiny, surreal sculptures by Frank Kunert.

And finally: weighing a baby albatross. (Thanks Leisa!)

All the best,
