Question

what are green crakers?
​

Answer 1

The green crackers do not have barium and strontium salts as constituents and so create less polluting particles. This means, however, that unlike earlier, the fireworks will have a limited colour palette, producing mainly white and yellow sparks.

Answer 2

❤The scientists have developed three types of firecrackers – named Swas, Star and Safal – after a year's research. The commonly used pollution-causing chemicals – aluminium, barium, potassium nitrate and carbon – have either been removed or sharply reduced in the green crackers to reduce emissions by 15-30%.❤
