A black powder with amazing properties indicating that we may not be very far from realizing what we've been reading about in science fiction novels. Just add a pinch of this powder to anything to make it more than100 times stronger. This black powder actually consists of tube shaped molecules made of carbon. Like other forms of pure carbon it gets its strength from the strong bonds between carbon atoms. Adding only a few grams of this powder can greatly improve the quality of almost any product while reducing its weight. So we can have stronger buildings cars and even it is possible to weave super-strong bulletproof fabric. The Carbon Naotube promises to revolutionize many industries. Still a hot topic in the world of nano-technology since it was discovered in 1991 the continuous production of carbon nanotubes remains a challenge for scientist worldwide. Iran has managed to take a leap. In the research institute of petroleum industries it has taken the scientists 10 years to produce these nano tubes. The continuous production of up to 20 kilograms of Carbon Nanotubes is now possible in the institute using the Iranian designed reactor which has slashed the time required to synthesize this amazing product to 15 times less than similar procedures worldwide. The ten member team working on this project prepared to share the technical know-how they've acquired in order to heat hydrocarbon gases to 800 to 1000 degrees Celsius with the right catalyst to start the formation of the tubes. Molecules one-sixth the weight of steel but 100 times stronger. In fact the strongest material ever discovered with huge applications The successful completion of the pilot project to synthesize continuous carbon nanotubes will now be taken to the next level. Iran's private sector is already negotiating to establish units capable of producing up to 100 kilograms a day only to imitate what mother nature ha been doing for 100s of millions of years… engineering strength into the bodies of molecules one atom at a time.

1.Try to balance the textbook on a rolled up piece of paper. Use whatever method you want, but we\'ll bet you can\'t do it! Try rolling the paper up, making an arch... try everything. 2. Now roll the paper into a cylinder, length-wise, and wrap a rubber band around the tube to hold it in shape. 3. Now try balancing the textbook on top of the paper cylinder. Like magic, the tube can now support the entire weight of the textbook! 4. Looking at the cylinder, you might think the paper cylinder could support way more weight than just the textbook. There\'s only one way to find out! Find other items to balance on top of the text book. It\'s probably a good idea to keep the items unbreakable, because at some point, you\'ll have too much weight on there. 5. How many items were you able to get on top of the paper cylinder before it collapsed? Take all of those items to a scale and get a weight. Holy fright, that\'s a lot of weight… all balanced atop a piece of paper! How does it work? The average weight of a standard, flimsy, white piece of printer paper is less than 1 gram, right around .7 grams. It would make sense that something that light isn\'t able to hold the weight of a text book. Just trying to balance a textbook on top of the paper doesn\'t work… the paper just collapses! This is because the paper is unable to keep it\'s shape. It wants to return to a flat piece of parchment. With the addition of a rubber band, though, the paper can support and balance the textbook, and a whole lot more! The secret to the paper\'s new found strength is the geometrical shape known as a cylinder. Cylinders are one of the most structurally sound, and strongest, geometrical shapes. Cylinders are able to be incredibly strong, regardless of the material they\'re made out of, because they disperse stress throughout their entire shape. If the rolled-up piece of paper were a perfect cylinder, the strength would be even stronger!

Bubbles are cool, but bubbles filled with fog are even cooler. Get excited for some dry ice fun with this do-it-yourself Boo Bubble generator! How does it work? Dry ice is frozen carbon dioxide. When you drop pieces of dry ice into water, you get a wicked-cool combination of carbon dioxide gas and water vapor that bubbles out of the water. The creation of gas inside the two liter bottle quickly becomes too much volume for the two liter bottle to contain and the dry ice smoke flows over. By capping the two liter bottle with a funnel, the smoke builds pressure as it is forced into a more confined area. This pressure pushes the smoke through the tube, creating a flow of smoke that fills the bubbles. Steve Spangler combined the idea of filling bubbles with dry ice fog with his Bouncing Bubble activity to create a Bouncing Boo Bubble. While blowing bubbles indoors, you might have noticed the occasional bubble that fell to the carpet but didn’t pop. Regular bubbles burst when they come in contact with just about anything. Why? A bubble’s worst enemies are oil and dirt. Boo Bubbles will bounce off of a surface if it is free of oil or dirt particles that would normally break down the soap film. They break when they hit the ground, but they don\'t break if they land on a softer fabric like gloves or a towel.
