Awesome Science
Acoustic Fire Suppression
DARPA demonstrates technology which can extinguish flames using a pair of speakers and sound. As the acoustic field increases air velocity, the flame boundary thins and disrupts the fire.
Levitating Lightbulb
Using electromagnetism and wireless power transfer, engineering student Chris Rieger shows off a seemingly magical effect of a light source that floats in mid-air with no built-in power source.
Transit of Venus: Up Close
If you missed the once (or twice)-in-a-lifetime Transit of Venus in front of the Sun, here’s the best view ever, captured by NASA’s Solar Dynamics Observatory, captured in glorious high-def.
Garbage vs. Volcano
Ever wondered what would happen if you dropped something into the molten hot lava of a volcano? Here we see what happens when a bag of trash (mostly food garbage) plummets to a fiery death.
Blind Spot-Free Mirror
Drexel U. math professor Dr. R. Andrew Hicks created this mirror which provides a distortion-free 45 degree field of view by turning numerous tiny mirrors into one larger mirror, like a disco ball.
Extreme Water Repellant
Good Chemistry
10th grader Eli Cirino was asked by his chemistry teacher to make a video that explains the basics of chemical bonds. Eli ended up making something much dorkier and sweeter than that.
How to Measure the Universe
Why not take a break from wasting time on the internet and learn something? The Royal Observatory Greenwich explains the geometry, math, and optics used to measure objects in space.
Mind-Controlled Robot
Cathy Hutchinson suffered a stroke 15 years ago, and is unable to move her limbs or speak. Using a neural interface called BrainGate, watch as she is able to use her thoughts to control a robotic arm.
Why is Yawning Contagious?
Don’t get bored or sleepy while Vsauce shares some facts and theories about yawning. The leading theory why humans yawn maybe more intense than you think, but it actually makes sense.
121-Megapixel Earth
The Russian Federal Space Agency’s Elektro-L satellite captures astounding 121mp images of the Earth. In this video, we get a time-lapse comprised of color-enhanced shots. Hi-res pics here.
Water & Sound Illusion
By dripping water in front of a speaker, brusspup creates the illusion that the water has frozen in mid-air. And by changing the frequency, he can make it look like the water is flowing backwards.
Folding Paper
While we learned from the Mythbusters that folding paper more than seven times isn’t impossible, but extremely difficult. But if you could fold it 45 times, guess what would happen?
World’s Quietest Place
Orfield Labs has an anechoic chamber that absorbs 99.9% of sound but becomes unbearable after just 45 minutes. Apparently having no external noise to reference causes your mind to hallucinate.
James Cameron’s Deep Sea Dive
In a high-tech submarine armed with 3D cameras, the director is diving solo 36,000 ft. down to the deepest point on Earth. No man has been in 50 years, and they couldn’t see through the silt.
The Most Astounding Fact
Superstar physicist and TV host Neil DeGrasse Tyson responds to the question, “What is the most astounding fact you can share with us about the universe?” Watch the original interview here.
The Periodic Table Table
We’ve seen a periodic table of tables, but this one’s more impressive. Wolfram Research co-founder Theodore Gray made this wooden table and filled each drawer (and his office) with element samples.
Melting Spoons
Looking for a cool parlor trick? Watch this metal spoon completely disintegrate as it’s stirred into water. The trick? It’s made out of 99.998% pure gallium, which melts at 86°F. Try it yourself here.
Science Nation Army
The Inside Knowledge Project took random lab equiment and turned it into instrumentation for the classic White Stripes tune – though it would have been cooler as a live performance.
Miniature Chamelons
Researchers near Madagascar have discovered chameleons that measure in at just 29mm long when fully grown. We’re still waiting for microscopic polar bears we can have as pets, though.
Knittin’ Needles in Space
When ISS astronaut Don Pettit whips out a pair of needles in orbit, he’s not making a blanket, he’s demonstrating the strange forces at work when you combine static electricity, water and zero-gravity.
