Well Hello there Mi Bellos.

"Chemistry is a class you take in high school or college, where you figure out two plus two is 10, or something. "---Dennis Rodman 

Chemistry isn't as boring as it may seem,here we will provide you enough erudition along the way and make you experience a pleasurable way of tutorials about chemistry.Not your typical tutorial site >:)

See for yourself.

Speaking words of wisdom :)

"The meeting of two personalities is like the contact of two chemical substances: if there is any reaction, both are transformed." 
— Carl Gustav Jung

"With someone you like that much, the lows are as low as the highs are high. Does that make sense?' 
It does. It also makes me sound bipolar.' 
Love will do that to a person." 
— Simone Elkeles

"No, this trick won't work... How on earth are you ever going to explain in terms of chemistry and physics so important a biological phenomenon as first love? " 
— Albert Einstein

"Let me tell you, you either have chemistry or you don't, and you better have it, or it's like kissing some relative. But chemistry, listen to me, you got to be careful. Chemistry is like those perfume ads, the ones that look so interesting and mysterious but you dont even know at first what they're even selling. Or those menues without the prices. Mystery and intrigue are gonna cost you. Great looking might mean something ve-ry expensive, and I don't mean money. What I'm saying is, chemistry is a place to start, not an end point." 
— Deb Caletti (The Secret Life of Prince Charming)

"I get so breathless, when you call my name, 
I've often wondered, do you feel the same? 
There's a chemistry, energy, a synchronicity 
When we're all alone." 
— Corinne Bailey Rae

"Scientist believe in things, not in person " 
— Marie Curie

"Chicken fizz! O Lord, protect all of us who toil in the vineyards of experimental chemistry!" 
— Alan Bradley (The Sweetness at the Bottom of the Pie)

"On the stage Tristen bent over the piano, his fingers swift and sure, his blond hair gleaming under the spotlight. I glanced around at the audience, watching their faces, gratified that they were as captivated as I was by the dark, thunderous song that Tristen conjured."

Did you know?

If you slowly pour a handful of salt into a totally full glass of water it will not overflow. In fact, the water level will go down.

Each time lightning strikes, some Ozone gas is produced, thus strengthening the Ozone Layer in the Earth's atmosphere.

 

An ounce of gold can be stretched into a wire 80 kms (50 miles) long.

The noble gas Xenon lasers can cut through materials that are so tough even diamond tipped blades will not cut.

The only letter not appearing on the periodic table is letter J.

A bee sting is acidic and a wasp sting is alkali.To treat a sting by one of these you should use the opposite type of chemical.

Chemistry- Fun, Facts, and Things To Do

---

 So enough with the thoughts that chemistry is just all about elements and brain draining ideas,see how fun it is.

Listed below are some fun things to think about and some fun things to do.

• Consider the shape and design of the atom. It has a center (nucleus), some space and then an outer layer (the electrons). Look at all of the examples in nature that follow that design. How about the earth with it’s core, mantle and crust? How about the solar system with it’s sun, planets and stars? Think about Saturn, a planet, space and rings. An egg has the yolk, white and shell and cells have nucleus, cytoplasm and membrane. Can your child think of more examples?
• Discuss with your child the fact that you already conduct chemistry experiments everyday by cooking (liquid to gas) when boiling water (or sometimes in my case, liquid to that nasty black stuff at the bottom of the pan). When we boil an egg, it turns from a liquid to a solid!
• Have your child draw an atom and label it. Repetition is the key to remembering all these terms.
• Have older kids write a story about shrinking down to the size of an atom. Think of all the things they could do, and could not do.
• Talk about subatomic particles. What are they, you ask. The word sounds confusing, but it’s not. A subatomic particle is just the individual pieces of an atom. The electron, proton and neutron are all subatomic particles.
• Scientists believe that 90% of the entire universe is made up of two types of elements: hydrogen and helium!
• The plant hydrangeas only produce pink or white flowers in an alkaline soil, and blue flowers in an acidic soil. Now would be a great time to make that acid/ alkalis dyed T-shirt. Follow this link for instructions and a detailed explanation of how it works.http://www.themestream.com/articles.1692...
• Ants are very acidic.....so are tea leaves. If you ever get lost in the woods, don’t eat too many ants, or you will suffer from acid indigestion!
• Neon is not just a nifty type of color, it’s an element. Neon is used in lots of those advertisement signs that glow.
• Helium is used in birthday party balloons, weather balloons and in blimps. Helium is lighter than our air, so it floats!
• Your body is made of 65% oxygen, 18% carbon, 10% hydrogen, 3% nitrogen, 1.5% calcium 1% phosphorus and 1% of 6 other elements.
• The capital of Minnesota is St. Paul. Sorry, just making sure you are paying attention.
• Have the little ones make their own mixture. They can mix pretzels, raisins and grapes.

Thomas Edison's last breath

Supposedly, Thomas Edison's last breath was saved in a test tube. 

The "last breath" of the inventor Thomas Edison can be seen on display in the Henry Ford Museum. According to legend, Thomas Edison's son, Charles, approached his father on his death bed and placed a test tube over his father's mouth as he breathed his last breath. He then sealed the test tube with a cork and sent it to Henry Ford, a good friend of his father. Ford kept the test tube, believing it to contain his friend's soul. 

If this seems too good to be true, that's because it is. However, it was years before anyone found out what the mysterious test tube actually was. 

Here's the real story. 
Henry Ford kept some of Thomas Edison's personal items after his death, including his hat, his shoes, and a sealed test tube. After Henry Ford died, the Henry Ford museum put Ford's possessions on display, including the mementos from Thomas Edison. 

In 1978, Thomas Edison's personal effects were discovered, along with a cardboard mailing tube containing a sealed test tube and a note that stated "This is the test tube you requested from my father’s bedroom." The test tube was then put on display in the Henry Ford Museum with a label suggesting that it may be the dying breath of Thomas Edison. 

It wasn't until the late 1980s that we were able to find out the truth. The museum got a hold of a letter that Charles Edison had written to a radio commentator, explaining the origin of the test tube. It turns out that, in addition to being an inventor, Thomas Edison was also a fan of chemistry. He used to keep 8 empty test tubes by his bed, even when he was dying! His son, Charles, asked the doctor to seal the test tubes after he died, and he then gave one to Henry Ford, to remember him by. 

Neither Charles Edison nor Henry Ford ever referred to the test tube as containing Thomas Edison's last breath. Still, this legend was so fascinating that even "The Straight Dope" (a column that is otherwise a very reliable source for OMG Facts) got it wrong!
