Mercury thiocyanide {wiki} is the chemical once used in the fireworks called “snakes”. Burning it produces poisonous mercury vapors. So don’t try this at home! -via the Presurfer

    the rock was fun, but even more entertaining was the kids’ scripted acting at the end.

    Cool;

    We used to fire this, during festival times in India.

    Your video make me remember those childhood days.

    Thanks

    Very cool – just a quick note though for those wondering: those little black snakes you lit up as a kid do not contain mercury and they are still available AFAIK. The ones you probably lit as kids depend on Sodium Bicarbonate and are harmless.

    I’ve never seen a snake like the one in the video, but supposedly they used to be sold as the “Pharaoh’s Serpent” according to wikipedia.

    Oh man, I remember snakes as a kid. They were my favorite “kiddie” firework! I would light dozens of them at once and watch them fill the driveway with long trails of ash. They’d stink like heck, too.

    Wow. Total childhood flashback.
    I remember that lighting one at a time started to get boring so of course we just lit the entire box.

    The whole box at once? What happened?

    I long for my own personal bottle of orange ammonium dichromate.

    Apart from the mercury fumes, mercury thiocyanate is a poison in its own right that can be absorbed just by skin contact. I hope they washed their hands after touching it. The common firework version is made of nitrated naphtha pitch, and doesn’t contain any mercury.

    I wonder if anyone found this back in ye olde days and attempted to show it to people. I bet that was part of the reason for so many witch trials. :(

    All in all a very cool substance if not a little dangerous for your health.

    Nate–BWAAHAHA! We used to do that too! Then we got bored and started to experiment. We discovered that if you dumped out several boxes and stacked them into a huge pyramid, and then lit the top one, it would start a chain reaction that lit the rest down the line. You could keep the fun going for eternity with enough boxes!

    Mom banished us to the road after we filled the entire yard with sooty curls. Did you know that stuff turns into a black paste when it gets wet, and makes awesome shoe-prints all over freshly-cleaned carpet…? ;-)

    I can totally see ancient witch-priests dazzling the poor town-folk with this.

    But then Ali S. has a good point about the witch trials!
