Red displays come from Lithium, Rubidium and Strontium. These metals give different intensities in color and some even play other roles. Lithium and Rubidium are metals in group one of the periodic table. Lithium gives a medium red color and is most useful, for this purpose in its carbonate form. Rubidium on the other hand gives a deep red/ violet-red flame and is also used to oxidize the mixtures in these explosives; without oxidation, they will not burn properly. Strontium burns with an intense red but it also has the job of stabilizing the elements used to make the fireworks.
Blue displays come from Copper. Surely there are many who have seen a copper flame test in chemistry class, it is the same concept with these pyrotechnics, except on a much larger scale. Copper burns at low temperatures to produce a blue-green color and its halides form other shades of blue. Babies tends to learn faster with what they can play with. So rather than giving them just play toys, it will be wise to provide toys that they can play with while simultaneously educating them and developing early motor skills in your infants. We have selected some toys we found educative that will help improve your baby, engage them and educative them.

How Babies Learn It is quite surprising the rate at which babies learn and develop. Learning begins in the womb and continues throughout childhood. In early life how a child learns centers largely around the relationship with the parents. At least until the child starts preschool, the job of stimulating and satisfying babys desire to learn falls primarily to the parents. While babies respond to their parents voice there are many other sounds they find interesting. When parents are choosing educational toys for babies they should look for toys that have sound, colors that are bright and contrasted like red, black and white, and have interesting textures that babies like to touch.
Fireworks light up the sky during celebrations; they give a wonderful show of color and shapes that fascinate the eyes and minds of many. The beauty of the display often leads many to wonder where the colors come from. The short answer is that they are the result of the burning of metals placed in these explosives. These metals are elements of the periodic table that burn at different temperatures and give off colors at their melting points.
When it comes to the formulation of policies about higher education, structuring the system, financial assistance, grants and salary, the statutory body-University Grants Commission-is mentioned like a sacred cow worshipped as well as butchered in the streets. How far the UGC is autonomous is a common knowledge. It has become a post office, a government organization, disbursing petty grants, sanctioned by the Central Government, among universities or institutions with a number of tags attached to them depending upon the status of the recipient institutions, state, Central, autonomous or deemed universities. There is a perpetual complaint about the non-availability of funds. The administration should appreciate that the jumbo cabinet and expenditure on legislatures could be cut down to feed and educate a few villages. The teacher wants to be a ladder upon which students could climb and scale new heights.
