__**What is Super Glue?**__

Super glue also known as cyanoacrylate is a substance which is known and sold around the world. It was first discovered by Harry Coover from Kodak during the World War II, when he was trying to make gun-sight lenses out of the substance but always failed miserably because of the sticky compound that was made, which is cyanoacrylate. But, Harry Coover suddenly realized that cyanoacrylate made an incredibly strong bond without needing heat. So his team decided to stick objects together using cyanoacrylate and noticed that there was a use for this sticky compound. Harry Coover then made a patent for his discovery. Few decades ago the compound which was an accident and a huge failure became famous, a huge success, and an instant glue which we now call Super Glue. Back in World War II it was advertised under the name “Flash Glue” The use of this glue, is for making materials strong and durable. The associated compound 2-octyl cyanoacrylate is used as medical grade glues; it was established to be non-toxic, less irritating to skin tissue, and heal skin wounds. Cyanoacrylate glues are sometimes known as instant glues. The acronym CA is commonly used for industrial grades.



__**The Pros and Cons of Super Glue**__

__**Pros:**__

Cyanoacrylate can be used to assemble electronics, wire wraps, flying model aircrafts, and as coverings for nuts and bolts. Their efficiency in bonding metal and general usefulness has also made them popular between modeling and miniatures hobbyists. They are used to re-harden the boxes and heel of ballerinas' shoes as well. Not only they can fix objects and materials, but they can heal wounds around your body too!

__**Cons:**__ Even though they are really useful throughout our daily life, but there are also negative effects to cyanoacrylate. The gases from cyanoacrylate are a vaporized form of the cyanoacrylate molecule that irritates delicate tissues in the eyes, nose and throat. These risks can be reduced by using cyanoacrylate in well ventilated areas. About 5% of the population can become alerted with frequent contact with the CA gases, resulting in flu-like symptoms. It may also act as a skin irritant and may cause an allergic skin reaction. Using cyanoacrylate to materials made of cotton or wool (such as cotton swabs, cotton balls, and certain yarns or fabrics) outcomes in a powerful, quick exothermic reaction. The heat released may cause minor burns, and if enough cyanoacrylate is used, the reaction is capable of catching the cotton product on fire, as well as releasing irritating vapor in the form of white smoke. Material Safety Data Sheets for cyanoacrylate alert people not to wear cotton or wool clothing, especially cotton gloves, when applying or managing cyanoacrylates.

8 Neutralizing Stomach Acid - Thurka Thankathurai


 * Gastric acid, also known as Stomach acid is made up with combinations and mixtures of hydrochloric acid, potassium chloride, and sodium chloride.
 * Heartburn is when the Stomach acids get into the esophagus and eat away at the lining, causing the burning feeling.
 * Stomach acids are strong enough to eat through living tissues



13 Bioremediation - Kevin Dass


 * Contaminated land can cause the disappearance of animal and plant species that once used to live in the area.
 * Dumping of waste into water supplies, nuclear plant meltdowns can cause lands to be contaminated.
 * A process known as remediation can help clean land that is contaminated.

10 Mining - Fathima.B


 * The people who are exposed to the toxic waste from mine dumps become sick. They develop skin rashes, headaches, vomiting, etc.
 * Mining is a source of wealth for many countries such as Canada and Middle East.
 * Mining is very destructive to the environment because it is one of the main causes of forest removal or which is also known as deforestation.
