The chemistry of firework colours

Interactive viz


F is for FIREWORKS

For this weeks viz I consulted my youngest, a princess of 4 years old (going on 14).

Dad: “What do you like about fireworks?….”

Princess: “The pretty colours dad! they are magical. What makes them so pretty?”

Dad: “hmmm….fairy dust and unicorn poop”

Princess: “nahhhhhhhhh, your telling porkies!

Ok! she was quite right, I did’t really know to be honest, so I thought I would do a spot of googling and get back to her with a viz.

For this one I utilized the same technique I used for the Shackleton viz image, and if you whizz your mouse over the fireworks it makes them dance about the screen – quite like fireworks going off…… the resulting viz was actually received with a few ‘ohhhh’s’ and ‘ahhh’s’, which I took to be a success, as she isn’t normally interested in what I do to be honest…..
