Ah yes, I was going to add TechnologyConnections for sure, but someone beat me to it 
Such “random” but oh so interesting topics, I love it!

This is really cool. Thanks for sharing. Amazing how innovative is that soda can engineering. I wonder if this is the absolute pinnacle of perfection or if it has room for further optimization.
For science: Smarter Every Day.
For music: Rick Beato.
Engineering explained.
Okay so this might be “controversial” but I’ll post it anyway: I really like some/most of the documentaries of Vice, saw a really interesting piece on Cobalt mining recently for example. Sure sometimes it feels like there is a certain “agenda” in some of the videos but one just has to look through that 
If they ever successfully derive a personality AI from existing recordings, they should do Feynman… and use that AI to teach science courses.
Things I learned from MrBallen videos:
Don’t go scuba-diving, or you’ll die.
Don’t go caving/spelunking, or you’ll die.
Don’t go into the woods, or you’ll die.
Don’t go exploring mine shafts, abandoned warehouses, etc., or you’ll die.
Don’t go hiking/skiing/snowboarding/hunting/etc. in the wild, or you’ll die.
Don’t climb down chimneys, into crawl-spaces, into air-ducts, etc., or you’ll die.
And so on.
My life’s greatest ambition is to not end up in a MrBallen video.
Mr. Ballen has really good presentation skills. I watched the first 2 videos. Informative, entertaining stuff. Thanks, LB.

Technically not “learn something new”, unless you participate in these particular hobbies:
Luke Towan does absolute top-tier life-like dioramas and My Mechanics restores things with precision and finesse that would impress a Swedish watch maker.
Tom Scott. Random subjects that answer questions you didn’t even know were there to be asked.
he gets kind of “preachy” sometimes,
but fast-forward is my friend.
Speaking of which, this was pretty awesome…
He’s also got some good docs.
To keep it flashlight related
