How To Make Pharaoh Snake Fireworks (Patreon)

I'm currently preparing to teach some science demonstrations for local kids this summer and thought to try this giant black snake fireworks experiment to see if it would be a suitable thing to include. I've wanted to try this experiment ever since the first time I saw it but had forgotten about it until recently. Very simple, with an excellent result. I used a 4:1 ratio of powdered sugar to baking soda by weight for the snake mix, and isopropyl alcohol as fuel to wet the sand.
