Highlighter Reactions

In class we did this cool lab were we took a white piece of white paper and made a dot with a highlighter. Then we put the tip of the paper on a cup with water. We observed that the highlight color was going up the paper while forming different shapes. Each color forms different shapes. We also learned that FBI and the police uses this method of what the reaction will be to see if the pen (for example that a note was written) is the same as  the suspect's and if the reaction is the same it means the pen (for example is the same)

Reaction Lab

Reaction 1:
glue+boron+ water= GAK

In class we did two awesome reactions. The first one we created GAK by adding water (that had baking soda in it) to glue and then boron. I observed that at the first part of the reaction where we add    water to the glue that as we stir it, it gets thinker and starting to get sticky. When we added the boron and stirred it for a while, it became very sticky, thick, bouncy and stinky. This is a reaction because there is a change in the matter- from liquid it became solid through covalent bonding















Reaction 2:

cu2+so4+zn(s)=cu(s)+ zn2+so4


The second cool excrement, we saw that the zink becomes darker,  bubbles are created and it dissolves. This is a reaction because the matter changed color.

Air In A Can? Seriously?

By Meera Dolasia on September 30, 2012

Have you ever thought that you breath polluted air? Chen Guangbiao found the solution for your problem. It will only cost you 0.80 cents. This is a can that contains unpolluted air from place far away from cars that is it is 100% oxygen. That's because "Apparently each can contains a chip so that during the packaging process when the negative oxygen ions reach a certain concentration level and the can is full, it seals automatically". Another cool thing about it is that you can keep 'drinking' for a long time without it getting out 

I think this is really cool but also a waist of money. Maybe we could use this in the future when we don't have clear air to breath maybe we could use it. It also mentions on the article that he is a philanthropist then shouldn't he give it for free or donate it?

Russia's Shiny Secret - A Huge Treasure Trove Of Diamonds Inside Impact Crater


By Meera Dolasia, September 20, 2012

Back in 1970, when Russia was part of the Soviet Union, there was a diamond crater discovered formed by an asteroid that fell at that place thousands of years ago. They didn't use its worth since the Soviet Union was very rich and produced there own gems but now that it is in-depended they start using it. It can't actually be used to create jewelry but can be used for the creation of unbreakable glass since from the force that the asteroid hit the Earth, it can't be 'broken down'. According to the article,  it is a "supply that they claim is vast enough to fulfill global demand for at least, the next 3,000 years."
I think this is very interesting and can save Russia as a country if there is an economical need. The weird thing is that they knew that  the gem's existence for more that 20 years and they didn't want to tell the rest of the world which is really weird.

This Summer - Transform 'Nuisance' Ghost Ants Into Beautiful Gems

Meera Dolasia, August 3, 2012


Hearing the word ghost ants it comes to my mind a picture of ants that are almost invisible. And that's what they exactly are. But they have a little bit of 'magic' in them. Whatever they eat, you can see it at their back and legs. Well... just the color. An Indian scientist tested it because his wife told him that those ants came and drank the spilled milk and turned white. Putting colored sugar drops in a lab, he brought these ants at his labratory and tested them. And it turns out really cool. 
I think that this is really cool and very 'creative' from nature and since I hate ants because they are so annoying this article made me look at them from another angle.

Meat From Scratch


By Stephen Ornes April 12, 2012

-"How would you like you meat sir?
-Medium to well done sir.
-How many stem cells would you like in it sir?
-As many as possible for it to be healthy.
- It will be here in more than a decade sir.
-I can wait....
-And it will probably cost more than your house sir.
-I have enough money to pay for it."

That is probably the script for Mark's Post's appearance on TV where he will eat the first hamburger made out of meat....but not. His new invention is a meat made out of animal cells and nutrients. This will be a revolution for our environment and the population not only of people but of animals too. It is really difficult to be a vegetarian, not eating meet because you think it is like a murder and they are right. This new invention will make us all in a way vegetarians since you will eat meet but not by killing it. Scientists will take some of the animal's blood, mix it with nutrients and let it grow at the lab. Since our Earth's population has increased dramatically making the animal population decrease this will change everything. Scientists are still working on it and they will have the first sample of this meat at October when Mark Post- its inventor- will try it. This model will be finished in a couple of decades and when it is going to be finishes it will be both hard to find and hard to buy since it will costs more than the average American house cost.


This is really cool. This is a true revolution of meat for us  humans. I think that they will finish it earlier since the first test is going to be at October which means only one month from now.
