Magical Mercury (II) thiocyanate 

Mercury (II) thiocyanate is a white powder that creates a twisting solid (or serpent) when ignited. It is an inorganic compound so has been created with complex mercury ions that bond with the thiocyanate ions (sulphur, carbon and nitrogen). Carbon and nitrogen bond together to make cyanide, and any Mercury compound is toxic, so it’s pretty important not to try this one at home!

    That is totally amazing to watch. I am actually stuck for words to describe how awestruck I was watching the skeletal serpent emerging magically form nowhere!
