So we had Halloween last week and its Guy Fawks night on the 5th of November so I thought this week could be all about Fireworks.
- Different colours of fireworks are created by using different chemical compounds. Blue fireworks are created using copper and green are created using barium chloride.
- You see the explosion of a firework before hearing it because sound travels at 761mph, but light travels at 671 million mph.
- A firework shell can reach as high as 200m.
- The invention of fireworks led to the invention of pyrotechnic weaponry—not the other way around.
- Americans have been setting off fireworks to celebrate their independence since 1777.
- The majority of firework injuries happen at private events and then its often children under the age of 17 that are affected.
Hope you’ve enjoyed this minute of science. Stay safe this fireworks night!
