A simple, but fascinating construction that demonstrates the energy transfer that occurs when two pendulums are placed along the same string. Each one almost completely stops as its momentum moves to the other one like some kind of a seductive dance. (Thanks Kate!)
“There are more phages on Earth than every other organism combined.” Kurzgesagt takes a few minutes to educate us on the finer points of the bacteriophage, a type of virus which is constantly killing off billions of microscopic organisms all around and inside of us.
When it comes to holding things together, two of your best bets are glue or tape. Elizabeth Cox and TED-Ed explore the science behind adhesives, and which are the best for specific uses. We always wondered what kept glue from sticking to its own container, and now we know.
Engineer Mark Rober and teacher Al “Doc Fizzix” Balmer explain the physics of these primitive race cars that get their power solely from the energy stored in a mousetrap’s spring. Along the way, you’ll learn about the principles of mechanical advantage, levers, and wheels.
This super-fine steel wool reminds us of Donald Trump’s hair. But these skinny metal strands are most interesting when they have their electrons excited by a microwave oven. Steve Mould explains why it behaves so spectactularly. The 9-volt battery trick is pretty neat too.
You never want to get too close to a mound of fire ants. But from the comfortable distance of your browser, they’re neat little buggers. Vox explores some of the fascinating ways in which colonies stick together to form structures, and how they can act as both a solid or fluid.
Theoretically, the reason that whipped cream is thick is because of the air in it. So if you put it in a vacuum chamber and remove all the air, does it go back to the way it was? The King of Random sucks as hard as they can to answer the question none of us was asking.
Kurzgesagt explores string theory, and how it attempts to explain the nature of the universe. It’s supposed to solve the incompatibilities between quantum and gravitational physics by describing particles as “strings” rather than points. Yeah, we’re still confused.
Destin from Smarter Every Day teamed up with Gav and Dan from The Slow Mo Guys to see what exactly happens when a bullet hits a piece of bulletproof acrylic, both with a bullet that can’t make it through, and then with a .50 cal that can. Watch The Slow Mo Guys’ video here.
When your dog sits there and stares at the TV, do they see the same thing we do? According to this clip from SciShow, your pup’s probably sees something more like a flipbook in shades of yellow and green. Though they might actually enjoy the soap opera effect more than humans.
As George Carlin once taught us, there are no blue foods. It’s Okay To Be Smart explores the why there is so little naturally-occuring blue pigment in animals, plants, insects, and other organic matter. Oh, and those Morpho butterflies aren’t actually blue. Minds blown.
