Yesterday, the United States of America celebrated its  independence day. The 4th of July celebrations usually include massive displays of beautiful fireworks. In India, we often do not wait for Diwali to enjoy fireworks. We are happy with the Indian team winning in cricket to light up a few fireworks.

Did you know that the science of combining materials that produce chemical reactions resulting in  heat, light, gas, smoke and sometimes sound is called “Pyrotechnics”?

The science behind these enchanting fireworks is absolutely amazing. Here is a detailed piece by Kathy De Antonis which explains the phenomenon of fireworks in some detail.
