Sulfuric acid is mixed with sugar, which is attacked by the acid. The final products are carbon, water vapor, and sulfur dioxide gas.
Is this what happens when lightning hits sand? It turns out that when lightning hits sand, it makes little holes in it. Sadly, this picture was part of an internet hoax that circulated in 2013.
In 1997 Roberto Carlos scored a majestic goal against France by bending a ball through the air in a majestic way, so majestic the France goalkeepers stopped to watch !
A gyroscope goes into a bar, the bartender asks if he's drunk.
Science is not boring, not with Integza... THIS IS INTEGZA !!!
This video is compilation of ten amazing optical illusions: Rooftop Illusion, Color Illusion, Motion Binding Illusion, Crazy Wire Illusion, Duck-Rabbit Illusion, Silver Egg Illusion, Anamorphic Illusion, Water Illusion, Animated Optical Illusion.
Heavy Water & Light Ice Experiment. What happens? Ice floating over vegetable oil but it decreases in baby oil.
This requires a dry hen's egg at room temperature. Hold an egg near a candle flame to cover it with soot. It will need to be completely covered. This is tricky, because if the egg is a tiny bit damp the soot will easily flake off on to your fingers as you turn the egg. Once the egg has a nice black sooty coating, gently immerse it in a bowl of water.
Just how much "zero" is Zero? What happens if you boil these popular drink for 20 minutes or so? Watch this video and you'll be surprised by what you get after the water evaporates.
The trick in the video is that the magnets are made of a conducting material and they connect the battery terminals to the copper wire, so the battery, magnets and copper wire make a circuit that generates a magnet field just in the vicinity of the battery. The geometry means the two magnets are automatically at the ends of the generated magnetic field, where the field is divergent, so a force is exerted on the magnets.
Step 1: Make One Tetraeder You need 6 straws of the same length and a cord. Step 2: Add More and More Tetraeder in the Shape of a 3d Sierpinski Tetraeder
These are my favorite illusions. From one angle everything looks perfectly normally until you see the balls rolling uphill. When you change the angle
When the arrow is moved to a particular distance behind the glass, it looks like it reversed itself. When light passes from one material to another, it can bend or refract. In the experiment that you just completed, light traveled from the air, through the glass, through the water, through the back of the glass, and then back through the air, before hitting the arrow. Anytime that light passes from one medium, or material, into another, it refracts.
Interesting reaction coke and milk The reaction of phosphoric acid (V) to proteins in the milk - they are cut and causes a precipitate

Ever wonder what people used before toilet paper? Humans have been living on the earth for about 200,000 years. But toilet paper wasn't created until 1880. So what did we use before?

beautiful mathematics .amazing shaped hills with numbers formed in multiplication.watch it and show it to the children and students to make them interesting on mathematics.
It's been proven over and over that you can make batteries out of fruits and vegetables such as lemons, potatoes, and even apples. Turns out, passion fruit is also acidic enough to power a battery, but Maui Makers member Ryan K decided to take it a step further by adding a laser. Passion fruit, or Lilikoi as it's called in Hawaii, is usually over-abundant in Maui, so Ryan decided to put it to good use. Using anodized bolts, copper pipe, wire, switches, and some LEDs, he built a battery that c...
We've all played with bubbles as kids, but I think most would agree that they're not exactly the most functional of objects. An international team of researchers made up of Yoichi Ochiai, Alexis Oyama and Keisuke Toyoshima wants to change that. They've figured out how to project both 2D and 3D images onto a micro membrane (soap bubble) using ultrasonic sound waves and a standard projector. The bubble is made of a solution of sugar, glycerin, soap, surfactant, water and milk. The glycerin and ...
A couple months ago, the world was supposed to end. It didn't. But that didn't stop the Centers for Disease Control and Prevention (CDC) from warning citizens of one global possibility besides complete destruction—ZOMBIES. They used the farcical flesh-eating living dead as an excuse to teach you about the necessity of real-life emergency planning.
It's best known as a children's toy, but kids aren't the only ones who can appreciate the unique and marvelous properties of Silly Putty. It's an incredibly fun silicone polymer that almost seems like a scientific anomaly, thanks to its viscoelastic non-Newtonian flow. This amazing dilatant fluid can be stretched, torn and mashed back together, as well as bounce and shatter into pieces with a forceful blow.
They've been at it for a few years now, but the crazy group of amateur rocket scientists who call themselves Copenhagen Suborbitals have triumphed over adversity, successfully launching their DIY rocket nearly 2 miles into the sky last Friday. The privately funded, non-profit aims to one day send human beings into suborbital space on the cheap, without the need of government budgets and administration.
Transverse wave motion is the beautiful rippling effect that occurs when a moving wave causes oscillations that travel perpendicular to the direction of energy transferred. (For example, via Wikipedia: "If a transverse wave is moving in the positive x-direction, its oscillations are in up and down directions that lie in the y–z plane.")
Human anatomy is something every physician must undergo as a medical student. Some move on to become great doctors, some move on to become great artists, helping to better educate students and improve upon many illustrated representations of the human body since the days of medieval medicine. But thankfully, you don't have to be in the medical profession to enjoy the beautiful art of the human body created for teaching purposes.
While most people go to great lengths to conceal their emotions, Japanese company Neurowear is offering a product that would reveal states of tension, excitement and relaxation—all by the up-and-down motion of a pair of cartoony cat ears. Necomimi is a "new communication tool that augments human’s body and ability." The device reads your brain waves and communicates your emotions before you even open your mouth:
If you found the world renown Body Worlds exhibition gnarly and perverse, perhaps you'll find this latest parade of plastination a little less so—considering we don't share the same DNA as these specimens of jerky-in-the-name-of-science. The Koerperwelten der Tiere—or Animal Body Worlds–doesn't showcase preserved corporal matter, but rather 20 odd plastinated mammals, currently on display at the Cologne Zoo in Cologne, Germany.
