TheBackyardScientist shares a simple way to create a small fire tornado with no moving parts. The trick is to split the glass receptacle in half and place each half around the flame slightly off center. The wind that comes in through the gaps will create the tornado effect.
The 560th Flying Training Squadron invited SmarterEveryDay for a test flight in the trusty Northrop T-38 Talon, a supersonic trainer jet used by the US Air Force and NASA. It gives us a thrilling glimpse of just how hard it is to handle such powerful birds.
This footage may be 8 years old, but it doesn’t make it any less impressive. Watch as then high school student Anna Gu demonstrates a bridge she made from layered and glued sheets of paper that was so strong that the hook that held the weights failed before it did. Design here.
If you thought that machine that could balance itself on a single point was cool, check out Andreas Eder and Tobias Glück’s robot, which can swing three pivoting sections upright and keep them balanced. It can’t hold on indefinitely, but we’d like to see you do better.
Mike Rouleau shows off a neat bit of tech – a device which stands on a needle-like tip, but keeps itself balanced by constantly adjusting the direction and speed of motors. As one commenter put it: “Any sufficiently advanced technology is indistinguishable from magic.”
PBS’ It’s Okay to Be Smart considers the intellectual concept of a shrink ray, and how if it were even possible to turn us all into Mike Teavee, we’d end up dead in the process, since many of the systems our bodies rely on would fail to do their jobs in miniature.
A cool science demonstration which shows how the electrons swirling around the outside of a Tesla coil can turn it into an impromptu motor – in this case, causing a wire balanced on top of it to spin and shoot sparks as it goes. Originally seen in a video from ElectroBOOM.
Yo-Yo master Ben Conde joined science channel Veritasium and Beyond Slow Motion to demonstrate his ability toss a yo-yo into the air, let it spin without its string attached, then recover it. You’ll be entertained, and learn a thing or two about physics along the way.
Physics Girl and Arc Attack might sound like a superhero and her evil archnemesis, but they’re just everyday geeks who love science. Here, they show us how to rip an aluminum soda can to shreds using a powerful electromagnet, along with a couple of other fun experiments.
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.
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.
