A bear stole my GoPro! wave machines! and lava!

• Recently, I was sent a video idea about the world's largest wave pool. (Thank you, Nick W!) It looked like a great story — a strange, one-off, intimidating mechanism, indoors in a shopping mall. Big physical infrastructure. Interesting history. But then I found that the perfect video about it has already been made. I can't beat that! It's got behind the scenes footage, animations, and a great explanation, and I watched every second of it.
  
  And then to follow it up: the mall also had an actual submarine ride inside?! With genuine submarines, not like the fake ones at Disney Land? And somehow, this channel was able to put a camera inside the old pool to see how it's faring years after being shut down!
  
  And then the mall waterpark also had what looks like one of the best rapids rides ever made? And the channel's filming in the old, dry, decaying flumes, presumably with permission? This channel is called "Best Edmonton Mall", and it's been quite a while since I've been this impressed by a small channel. I recommend all three of those videos.
   
• I know most of my audience will already have seen it: but just in case you haven't, it's the return of Map Men Map Men Map Map Map Men Men Men.
   
• Tibees runs through time travel in physics textbooks, which is a lovely way to introduce a lot of concepts very quickly!
   
• Yes, I know there's a new volcano in Iceland! I can't get to it! But Isak Finnbogason is on it, with livestreams and spectacular video from his drone. Check the "live" tab to see if he's live and in the air right now, and if not, have a look at the spectacular footage he's taken this week.

• Floors! I know, that doesn't sound like much, but this is a really interesting deep-dive from London Reconnections into the art and science of designing wayfinding signage for floors in rail stations.
   
• Remember the Even Given, the ship that got stuck in the Suez Canal? The accident report is out, and the summary from gCaptain is worth reading; it shows off just how many things were wrong on that day. (The full report's linked at the bottom.)
   
• The man who investigates cheating in marathons and other long-distance races.
   
• It's been ten years since Google Reader was killed off, and this is the story of the people who built it.

And finally, a hundred people scream as loud as they can (strong language). Or at least, they try to.

All the best,
