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.

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.
