The Pharoah's Serpent -- Mercury Thiocyanate

(YouTube Link)

The Pharaoh's Serpent is a traditional pyrotechnic and chemical display in which mercury thiocyanate is set on fire, producing what looks like a very rapidly growing vine. It has since fallen out of favor due to the toxicity of mercury, but sodium bicarbonate produces a similar effect. The video above is a demonstration of this visually stunning chemical reaction.

Here are instructions for making Sodium Bicarb snakes. Looks like they aren't quite as awesome as the old, toxic ones.

We used to make a big pile of the old ones and light them all at once. With enough tablets, you could crack a sidewalk. God knows what the fumes were doing to us.
