He Pours Milk Into A Bottle Of Coca-Cola. Minutes Later The Results Blew Me Away!
Most people have seen and are familiar with the Coca-Cola and Mentos reaction, but wait until you see what happens when you combine Coke and milk. The results are both stomach churning and fascinating at the same time. First, you open a plastic bottle of Coke and then add a small amount of milk to it, being careful to leave a little space between the top of the liquid and cap.
Secure on the bottle cap and gently agitate the liquid by moving it back and forth a few times. Now the wait begins. The entire process takes about an hour but make sure to watch it at 5 or 10 minute intervals to see the change take place. When it is all done you probably will not be craving a soda anytime soon!
So what is actually happening in this mini science experiment? The process is due to a reaction of the Coke’s phosphoric acid with the milk. The phosphoric acid molecules bind to the milk which gives them a higher density and causes them to separate out and eventually sink down, while the remaining liquid from the milk and Coke, being lighter, floats to the top.
Those solid particles you see are actually curdled milk. Because the soda is more acidic than the milk it causes it to separate into curds and lumps, aka the textbook definition of what it means to curdle. To better illustrate this, Coca-Cola’s pH is between 2.5-4.5 and milk’s pH level is almost neutral (7 being neutral) at around 6.7. Thus, the Coke’s higher acid content binds to the lower milk ones and causes them to separate.
Due to Coke having such a high acid content people have been using it for years as a cleaning agent. It can take tarnish and rust off metals and even degrease car engines. Add it to your toilette to get it sparkly clean or wash your laundry with it to remove stubborn stains. Better yet, if you or a pet ever get sprayed by a skunk, just pour Coke on the stinky spots and it should smell better almost instantly. The uses for Coke are many but one is a definite no-no and that would be mixing up a Coke-milk cocktail.

Have You Ever Noticed This Tiny Hole Above Someone’s Ear? This Is The Strange Reason Why It’s There.

If you have ever noticed that someone has a tiny hole above their ear, that looks like it could be a misplaced dimple, you may have assumed that it was from some odd type of piercing. However, what you actually picked up on is a body feature that happens to be a naturally occurring mutation in some people. And while the little hole is not all that common in America, it’s more prevalent than you’d imagine it to be.
Those tiny holes are best known as preauricular sinuses and they are located right around the junction where the top of the external ear cartilage meets the face. They are considered birth defects and get passed down from one generation to the next. The holes can occur on one or both ears, with the right side being where they are more frequently found. For the most part they are harmless, but just like other types of sinuses, they can become infected and require treatment. Some may also form cysts and in rare cases draining or removal is the best option.
Why the holes are there in the first place and for what purpose remains mostly a mystery. The accompanying Business Insider video mentions an interesting theory put forth by Neil Shubin, an evolutionary biologist, who says that they could very well be an ‘evolutionary remnant of fish gills’. It’s an interesting idea and makes sense, but there could just as easily be another explanation for the holes.
The chances of a person being born with a preauricular sinus dimple varies across geographical and ethnic lines. Researchers in Korea found that the small dents are most common among Asian and African populations, where between 4-10% of people may have them. In comparison, less than 1% of Americans and those born in the UK are affected, which is far fewer. In Ethiopia, the teeny holes are considered lucky to have because they’re believed to bring people money and wealth.
If you didn’t know what those strange ear holes were before, now you know the basics about the auricular sinus. Please pass this on and help share it so that more people can learn about them and be informed!

The Amazing Health Benefits Of Eating a Pickle a Day According To a New Study

Pickle lovers everywhere can rejoice and dive deep into a jar of the yummy, salty, sour tasting cucumbers because it turns out that they’re better for us than previously thought! It’s not only pickles that do a body good, but all fermented foods and drinks can boost our health. So the next time you get a craving for something crisp and salty, snack on a few pickles and improve your social life in the process.
You’re probably wondering exactly how can a pickle make my life better and the explanation to that end can be found in a number of relatively new studies that have come out in recent years. In one study, completed by researchers at McMaster University in Ontario, Canada, hard evidence was found that the bacteria living in our digestive systems is directly linked to our brain chemistry and behavior. That means the trillions of bacteria in our guts can have a noticeable effect on our mental health and wellness.
Furthermore, researchers at the College of William and Mary found that young adults who ate a diet rich in fermented foods, such as kimchi, sauerkraut, other pickled veggies, kefir, kombucha and more, experienced lower levels of social anxiety than those who did not eat fermented foods. According to Matthew Hilimire, an assistant professor in the department of psychology who co-authored the William and Mary study, the fermented foods had an “anxiolytic effect” on subjects, which in layman’s terms means that they reduced anxiety.
The findings of these two studies can be linked because fermented foods are a major source of probiotics, which help stimulate the growth of healthy, beneficial bacteria in our intestines. That means pickles and other types of fermented foods can work wonders at balancing the bacteria found in our digestive systems. In turn, this can have a profound impact on our overall mood and state of mind because we now know that our gut health is essential to our overall mental health and wellness.
The brain-gut link boils down to this basic premise; a healthy stomach and brain leads to mood stability and therefore less anxiety, depression, and irritability. By simply eating more fermented foods you can positively boost your mental health and improve your social life. You’re less likely to feel so shy, self-conscious, embarrassed, or anxious around others, and that can only be a good thing.
The research into fermented foods is ongoing and scientists are looking at alternative ways to help treat anxiety disorders by ways other than medication. Perhaps in the future we will pop a pickle instead of a pill and that’s awesome!

Students Sent A Balloon With A Camera Into Space. But 2 Years Later They Reveal Its Beautiful Story.

Sometimes things and events that seem absolutely random in and of themselves can end up coming together to form one heck of a story. Whether it is truly random or fated to happen, this is one of those strange turn of events that turned out for the best.
In June a group of students sent a balloon to the edge of space over the Grand Canyon. Despite having planned out the detailed launch, and anticipating where it would eventually land, they were never able to find and recover the craft and the camera or cell phone attached to it.
However, two years later an eagle-eyed hiker in Arizona happened upon the wreckage and the long lost footage was found. The students put together a detailed video and shared it on YouTube so the world could enjoy the beautiful sights that were captured.
The short clip walks the viewer through the background events and all of the preparations that led up to the big launch. First the students tested the balloon with a parachute flight test by dropping it from a height off the ground.
Then they did trajectory planning, made computer models, planned out a custom designed structure, and printed it out in 3D. Finally the day came to send it up into space. The students started out on the road at nine in the morning and headed to a launch site 20 miles west of the Grand Canyon.
There they assembled the balloon and made some last minute adjustments to the spacecraft, switching on the GoPro Hero3 and cell phone which were attached to the chassis. At 10:46 it was launched and less than ten minutes later the balloon had already reached an altitude of 22,967 feet, which put it at a distance of 7 kilometers above Earth’s surface.
By the time an hour and twelve minutes had elapsed, the balloon was 86,558 feet up (26.4km). From that height the enormous Grand Canyon looks like a tiny feature way below on the Earth’s surface, and the curvature of the planet is clear to see. As the balloon spins around you can even catch a glimpse of the moon far off in the distance.
An hour and 27 minutes after launch the balloon reached its highest elevation, 98,660 feet (30.1km), and a clearer view of the Grand Canyon below is shown. That’s also when the craft began its violent descent back to Earth as slow motion reveals the moment the balloon popped and flew away from it.
By the time it landed upside down back on Earth’s surface among some dry grass scrub a full hour and 38 minutes had gone by. The video includes the computer models which show the launch and landing sites relative to the Grand Canyon, and the flight path trajectory as well. Despite these calculations and all of the planning, the students were unable to find the remains of their craft and the video of its journey.
Two years later the camera was found and picked up by a hiker in Arizona who tracked down and returned the footage to the team who launched it. They were able to recover the incredible video and the stunning images that it captured along its epic journey into the stratosphere and back down.
The reason why it was lost in the first place was because there was no cell phone coverage in the area it landed, which the students were relying on to track it down. They had looked at inaccurate coverage maps provided by AT&T and thus the cell never received a signal when it came back to Earth.
The hiker who found the wreckage ironically worked at AT&T. She brought it to a company store and they identified the phones SIM card and tracked down the owner to send back the footage. Check out the awe inspiring film and revel in the beauty that is our home, planet Earth!
