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.

That said, this reminds me of my childhood around the 4th of July. I'm guessing the toxicity of that is why I get so antsy about overlong videos.
honkey lighters, Hüsker Düs and don'ts. Cherry bombs, nipsy dazers, with or without the scooter stick? Or one single whistling kitty-chaser?
The resulting stuff would make a great sci-fi background for a stop-motion film or something.

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.
