The reaction depicted above, nicknamed the "Pharoah's Serpent," actually use to be a common classroom demonstration. It also use to be sold in stores as fireworks until people realized it's actually fairly toxic. As its name hints, it contains very poisonous mercury. Mercury (II) thiocyanate exists as a white solid that when heated, expands to become a brown solid due to its decomposition to carbon nitride. Sulfur dioxide and mercury (II) sulfide are also produced. Nowadays, if you want a similar effect but don't want to risk touching mercury, you can try making a "Black Snake" by heating a mixture of sugar and baking soda in a beaker.
