While we know it’s possible to extract natural colorings from food and other items, is there a way to completely remove its pigmentation and make it white? The Action Lab performed a series of experiments to test this, and provides a brief lesson on the physics of color.
Meet Arnold, the king of animated hypotheticals is here to explore what might happen to us if we actually could cure aging, and live at least 10 times longer we can today. The result isn’t all butterflies and lollipops. Also, nice segway to the sponsorship, guys.
Kurzgesagt looks at one of the many ways in which mankind is leaving its mark on our planet. Despite its usefulness, this man-made invention is one of the most destructive forces when it comes to the environment. But in some cases, it’s still better than other materials.
“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.
