Re: Ammonium Dichromate Volcano



Keith,
the original black snake, or Pharaoh's serpent, is mercury thiocyanate.
It is a white powder, insoluble in water but slightly soluble in methyl alcohol.
This and the Volcano are good exampes of how toxic were some plays for children -and their family!

Hi Trevor,
I can't vouch for the video, but my volcano was just like that and it
was only dichromate.
But thanks for raising an interesting point, and one that merits some
investigative reporting. Check out:

The snakes lit by the children at my house this 4th were made in China
and contained no list of ingredients. The snake-lighting was done
with adult supervision, but no special care was directed to not
touching the pellets, so I'm a little nervous. Snakes are easy to
light. Dichromate is not. I think I'm going to crush one up and see
if it hardens gum. I'll let you know if I come up with a Snakotype.

Is there a second chemical involved there? Or are those little snake
pellets they sell at the 4th of july made from AD? That was pretty cool.
