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.
Kurzgesagt wraps up 2017 with a follow up to its fascinating clip about the relationship between an organism’s size and the way it evolves. This time out, we learn how we might actually explode if we weren’t the size we were meant to be. Say, was that Barb at 1:30?
Modern image recognition technology is getting really good at identifying objects. But engineers at MIT CSAIL show us how simply playing with their textures can confuse the AI into thinking an object is something completely different than what it actually is.
If you’ve ever seen a glacier up close and personal, you know they’re a beautiful blue-green color that’s unlike just about any ice or water you’ve ever witnessed. It’s Okay to Be Smart reveals the science behind what we see, then gives us a 360º view inside an ice cave.
It’s not too hard to travel faster than sound, but amping things up to the speed of light is a whole other level. Life Noggin pontificates on the what might happen if we could exceed 186,000 miles per second. The whole slowing down light thing seems like a cheat though.
