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.

Teaching profession is devalued in the country because the teachers cant compete in our society, have no muscle power, are educated and hence behave differently. Neither do they have guts of creamy bureaucrats nor institutional support of any kind. A teacher can entertain you with a pale smile on hearing that this is the profession of nation builders, the cream of society and a noble profession. The next moment teacher will be branded as cancers in societal marrow, getting salary for no work, craving for power, equality in salary and status with the Class A government servants. The teacher was the consultant and conscience keeper of society till mid-century. One could identify him by his tattered clothes, emaciated pale face, soft voice and meek behavior. He was the guru. That guru, comparatively having a better outfit now, has metamorphosed to a present teacher.
The Central and state governments invoke ESMA to curb the voice of agitating people, but it takes no time to give benefits to politicians and bureaucrats. It is essential to please them so that a symbiotic balance is maintained as also to oblige a few of them. The government has failed to take effective steps to curb industrialization of education. Within hours the doles given in Parliament and honorarium were doubled but the 6 per cent expenditure of the GDP on education has proved to be dogma persisting right from the Kothari Commission recommendations for over four decades now.
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.
