How do they put the colour in fireworks?

“Remember, remember the fifth of November, gunpowder, treason and plot…”

Bonfire night is an annual celebration in Britain. It is celebrated on November 5th every year and marks the failure of a plan, called the Gunpowder Plot, to blow up the Houses of Parliament in London. It is tradition to mark the occasion by lighting bonfires and holding firework displays.

Fireworks were invented hundreds of years ago and are used for lots of different types of celebrations and festivals throughout the year. My daughters want to know more about how fireworks work and how do they make such bright colours in the sky?

Fireworks are small explosions that work because of chemistry – you can find out more about how by checking out this website or watching this video.

Inside a firework is a mixture of dry chemical powders that will explode when they get hot – usually when they are lit by a match. The explosion often makes a loud noise and some of the chemicals contain metallic elements that give out a colour when they burn. For example, sodium burns orangey-yellow, copper burns greeny-blue, and calcium burns red.

They might look pretty but because they explode, it’s VERY IMPORTANT to stay safe when there are fireworks around. Fireworks must be stored carefully and safely at all times and children should not play with them. Here are some tips for how to stay safe on bonfire night. And remember that the loud noises and bright flashes can be frightening to animals, so make sure you look after pets and other animals on bonfire night and at the times of other celebrations.

If you’re celebrating bonfire night, please take care and stay safe!
