As their name suggest Periodic Videos is obsessed with all things science and chemical.
In this latest video of their to go viral, the professor discusses liquid oxygen, and conducts an eye-popping experiment by dropping a a hot charcoal into a bowl of liquid O2.
The results, especially caught by a super slow motion camera, are glorious. The week old video now stands with over 325,000 views.
Popular educational and inspirational TED talks recently posted this excerpt from Frans de Waal’s full speech, and now it is trending again.
While discussing moral behavior in animals, Frans and his team conducted an experiment where two monkeys would receive the same payment of a cucumber slice for completing a task.
At first they are both satisfied with their cucumber. But when one of the monkeys is given an ‘expensive’ grape instead, his counterpart is disgusted with his measly cucumber and throws the piece in the face of the experiment technician.
The implications of the experiment are quite obvious.
In a genius marketing move, helmet company Shark Helmets made a very real Newton’s Cradle using people. Hanging upside down, five bikers wearing regular helmets recreated the physics of the popular science toy by banging their helmets against each other.
When the first biker is dropped, the kinetic energy traverses across the rest until the energy sends the last biker swinging up into the air.
But here’s the point. Afterwards, they all don Shark Helmets. The Sharks absorb so much shock, the experiment no longer works. Now that’s advertising in action.
No matter where you are in the civilized world, it seems the same social problems persist. Homelessness is of course one of the most glaring issues around the globe.
Most people offer their change or few bucks to the unfortunate when they happen upon them on the streets, almost as an automatic reaction.
But how would people react when an apparent homeless man starts offering them money?
Greg of Mediocre Films thought it would make for an interesting social experiment. He recruited his actor friend Bruce to dress as a homeless person would, and instead of asking for a buck, he offers passersby money.
Some people take the money with a smile, but most are apprehensive to accept any gifts from someone seemingly less fortunate than them.
As a kid, Mark Rober–who is viral video famous for his road kill experiment–grew a seriously rocking unibrow. But through high school he discovered the magic of tweezers, and by the 12th grade, he had blended in with the general population.
For years now, Mark has suspected that people with unibrows are discriminated against. As a man of science, he was determined to test out his hypothesis in a controlled manner.
He teamed up with his make-up artist friend who gave him a perfect looking, fake unibrow. Then he approached people at Walmart with simple, open-ended questions. As a control, he did the same with normal eyebrows.
After his inevitably short conversations, the test subjects would almost always comment about Mark’s unibrow.
After breaking down the numbers, Mark discovered the average response he received while ‘normal’ was over 30 words. While he was wearing his fake uni, it was only 16.
Scientifically, it is a possible to claim unibrow discrimination is real. Someone call the ACLU!
Also, teenage girls are way too liberal with their smart phone cameras.
