Some of the popular metals for fireworks include: Lithium, Rubidium, Strontium, Copper, Aluminium, Magnesium, Beryllium, Antimony, Titanium and many others. Burning these gives a wide variety of colors and makers of these products combine them based on the type of display they want. Below are specific examples of the different colors given by different elements.
3 to 6 Months: During this stage your baby will gain better head control and have better movement of arms and legs. They generally grip onto anything they can get their hands on and put it directly into their mouth. Educational toys like rattles promote motor development and provide sensory stimulation. Since everything ends up in the mouth, educational toys that are chewable or soft plush are favorites. Babies need to experience different textures so vary the materials educational toys are made of. Activity centers provide lots of stimulation at this age. These educational toys normally have lots of buttons that produce sounds, lights, and give a variety of textures to explore. Hand-eye coordination will improve as babies explore the activity center. Parents are often on the move more with babies at this age. Activity bars that fit across a stroller, car seat, or bouncy chair that have dangling, squeaky toys and mirrors keep baby stimulated while on the move. Motor skills develop as baby reaches, hits, pulls, and kicks at the accessories on these educational toys.
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. Great educational toy choices for this age include character toys, puppets, dolls, toy vehicles, and animal figures. These educational toys foster creativity and imagination by allowing your child to create wonderful adventures, model adult behavior, and role-play. Large piece puzzles are great educational toys for this age. Children at this age should be able to complete a 4 to 6 piece puzzle on their own. Puzzles are a great activity to build hand-eye coordination, problem solving, and fine motor skills.
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.
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.
