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.
1 to 2 years: With each step your baby becomes more independent and confident. Little ones at this age spend every waking hour exploring and experimenting. For those still a bit unsteady walking, educational toys that promote mobility such as a walker or push car are great choices. Pushcarts and wagons are a great way for children to tote things around- another favorite activity at this age. Educational toys including soft plush toys and dolls remain favorites at this age. Children often become very attached to one or two and use them in creative play. Toddlers can find many ways to make loud sounds. Musical instruments like drums, maracas, and tambourines are educational toys that will help them learn to appreciate music while they make noise. Inset puzzles require toddlers to lift out pieces and find the right places to put them back. These first puzzles improve problem skills and fine tune motor skills. Puzzles are educational toys that your children will play with over and over again.

Even after half-a-century of Indian Independence, the fate of education, educators and students has hardly improved. The apathy of the power that be, including a large section of society, has not changed when it comes to human resource development and education. Even now there are more than four crore educated unemployed.
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.
