Fourth of July is a day for celebrating America’s independence, but is also a day for watching fireworks, which would not be possible without science!
Read on to learn more about the chemistry of fireworks, their history and a few other interesting science fun facts.
The Chemistry of Fireworks
‘Salt’ as a word conjures up images of the normal table salt you probably use every day; whilst this is one type of salt (sodium chloride), in chemistry ‘salt’ refers to any compound that contains metal and non-metal atoms ionically bonded together.
