Our smarty pants friends at Kurzgesagt examines the idea of human exploration, and some of the currently known limitations of space travel, physics, and our own bodies which prevent us from traveling to an unfathomable portion of the great unknown.
Smarter Every Day’s Destin Sandlin takes on a tweet by Neil deGrasse Tyson in which he stated that a stalled helicopter would land like a brick. Destin and pilots Brad and Gerry Friesen not only put their lives on the line to test this, but prove that nobody is right 100% of the time.
While he was hanging out at the pool with The Backyard Scientist, engineer and YouTube celeb Mark Rober conducted a scientific experiment which demonstrates whether it’s better to be underwater or on land to escape a grenade blast. The results might surprise you.
The Backyard Scientist continues his literally and figuratively sloppy experiments by “testing” oobleck (cornstarch mixed with water). Like ketchup, quicksand and silly putty, oobleck is a Non-Newtonian fluid. It flows like a liquid but behaves differently when force is applied to it.
It used to be that most airplane wings were straight, but it turns out the design caused instability as flight speeds increased. Real Engineering takes a look at the science behind the swept wing design which is commonplace on today’s planes. Learn more here.
While that title might sound like hyperbole, it is the truth. If concrete truly did dry out, it could be reconstituted with water like dry pasta, and couldn’t be used to build things. MinutePhysics explains the not so subtle differences between something being “dry” and “set.”
Grand Illusions shows off a physics plaything that demonstrates the differences between the shock absorbency of different metals, with one side coated with a special amorphous metal which allows a bearing to bounce like mad off its surface. More here. (Thanks Paul!)
If you’ve ever been clocked on the head by a golf ball, you’d be certain they’re hard as a rock. But they’re actually quite pliable. Here’s slow-mo footage of a golf ball as it hits a steel wall at 150mph. While it’s likely it was a practice ball, a regular ball still flexes quite a bit.
Beyond Slow Motion picked up a stack of colorful Magination magnets, then captured how dropping a single one into the mix causes them all to pull together toward each other. By adding some water and colored powder to the mix, the effect is even more impressive.
The Earth is constantly spinning to the East at about 1,000 mph, so you’d think that it would take basically no time to fly from East to West. Minute Physics explains why this isn’t the case, which is basically the same reason we’re not all constantly in motion.
Gav and Dan of The Slow-Mo Guys take something as simple as a foam ball soaked in water and turn it into a yet another fascinating subject in front of their 1600 fps camera lens. The spiraling water flying off the ball it look like a spinning planet with orbiting rings.
