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.
6 to 12 Months: Your baby has much better control over arm and leg movement. By 9 to 10 months, your baby should be able to move around by some means- either pulling, crawling, or scooting. By 12 months they should be able to stand by themselves and many will even start walking. Educational toys including wooden blocks that baby can stack and knock down, throw, or bang together to make noise are good choices. By 12 months, educational wooden blocks can be used for early construction play to promote development of motor skills, cause and effect, sensory and visual stimulation. Educational toys like the Sensory Ball from Edushape, provides great stimulation with different textures. Once babies learn to sit up, they will enjoy rolling a ball and trying to catch it as you roll it back. Letting your baby chase the ball will encourage movement. Trying to figure out why a square block wont go through a round opening will help develop problem solving skills- though it may cause some frustration in the beginning. By the time your baby is 12 months, they will start to enjoy stacking activities, though they will need help in trying to get the right order. More interest in books will be noticeable now. Try to buy books that have pages with different textures and simple flaps. This will help to develop their sense of touch.

Students of various educational institutes go on strike, almost yearly, demanding withdrawal of excessive fee hike. The tuition fees make up only about 13 per cent of annual expenditure in the present university education. It is now a formidable industry and the aim is to make money. Poor students, however, intelligent they may be, cannot afford to join colleges, professional institutions or courses. They may join such courses by putting their families under heavy debt of banks or financial institutions. Even in the USA, tuition fees contribute to about 15 per cent of the total annual expenditure on higher education. Nehru said: If all is well with universities, it will be well with the nation. Whereas Rabindranath Tagore once compared educated classes in India to A second storey in an old building that was added in, but unfortunately the architect forgot to build a staircase between them.
Though it is a constitutional obligation, the non-availability of funds and vested administrative setup have led to the mushrooming of universities, fake campuses, private enterprises and numerous makeshift centers of education as also fly-by-air foreign campuses. It has proved to be a great financial endeavor with hardly any risk involved because it does not come under VAT or any other financial constraints. India has by now more institutions of such type than colleges, an excellent opportunity to rope in knowledge seeking youth and those who desire to fly off to greener pastures.
Sounds Babies respond to sound and some of the best educational toys include rattles and musical toys. Soothing music such as lullabies is usually best. Auditory and musical toys are known to stimulate logical thinking and imagery in babies and in adults for that matter. One good educational auditory toy is the Electronic Metal Keys. These keys are good for a child 6 months and up. The Electronic Metal Keys are an imitation of the parents car keys. 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.
