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.
2 to 3 Years: Your toddlers motor skills are now well developed. They can run, jump, and climb. The area of explosive development in this stage is speech and language. Imaginative play becomes the focus for this age group. Educational toys that children use as props in pretend play help build language and communication skills.

However, the Electronic Metal Key toy is safe for the child to chew on and has a push button that emits sounds like a car horn, doorbell, ignition, and remote control door.
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.
