Watch a single cell become a complete organism in six pulsing minutes of timelapse. A film by Jan van IJken. Native to central and southern Europe, the amphibious alpine newt breeds in shallow water, where its larvae are born, hatch and feed on plankton, before sprouting legs and moving to land. This timelapse video from […]
Blue Origin was founded by the Amazon foudder Jeff Bezos back in 2000, and since then, the company has been testing several prototypes of its spacecraft. Now, after 15 successful test flights, Blue Origin is finally ready to put its creator into space. Watch live as Jeff Bezos, his brother Mark, 82-year-old aerospace pioneer Wally […]
This animation shows a ball dropping from 1000 meters to the surface of each object, assuming no air resistance. This should give an idea for the pull you would feel on each object. It might be surprising to see large planets have a pull comparable to smaller ones at the surface, for example Uranus pulls […]
From The Action Lab: In this video I elaborate on why a slinky floats in mid-air as the top of the slinky falls towards it. I show you how the center of gravity falls as expected once the slinky is dropped with a ball dropping at the center of gravity. Then I show you that […]
From Nick Uhas: I’ve done this reaction many times before. I did it for the Today show, America’s Got Talent, and a ton of live shows. So I’m pretty familiar with it, to say the least. And after our Elephant toothpaste experiment, I started thinking about other things we could do with the lifeguard tower […]
If you stick water in the freezer, it will take a few hours to freeze into ice. How is it, then, that cold packs go from room temperature to near freezing in mere seconds? John Pollard details the chemistry of the cold pack, shedding light on the concepts of energetics and entropy along the way. […]
66 million years ago, maybe on a Tuesday afternoon, life was the same as it had been the day before or a thousand years before or pretty much a million years before. Things were good for our feathered dinosaur buddies. Until a tiny, tiny detail in the sky changed. [In a Nutshell]
NASA’s Perseverance Mars rover used its Mastcam-Z imaging system to capture this 360-degree panorama of “Van Zyl Overlook,” where the rover was parked as the Ingenuity helicopter performed its first flights. The 2.4 billion-pixel panorama is made up of 992 individual images stitched together. The images were taken between April 15 and 26, 2021, or […]
Here is what happens with you bounce a ball on one of the world’s bounciest surfaces. And yes, you can easily do this at home! Watch the video to find out how! [Action Lab Shorts]
