A long snake-like shape of carbon formed during the experiment "Black snake" is a term that can refer to at least three similar types of fireworks: the Pharaoh's snake, the sugar snake, or a popular retail composition marketed under various product names but usually known as "black snake". The "Pharaoh's snake" or "Pharaoh's serpent" is the ...
A column of porous black graphite formed during the experiment. Carbon snake experiment. The carbon snake is a demonstration of the dehydration reaction of sugar by concentrated sulfuric acid. With concentrated sulfuric acid, granulated table sugar performs a degradation reaction which changes its form to a black solid-liquid mixture. [1]
Because of this, a heptazine-based structure similar to Liebig's melon, a compound initially prepared around the same time that the pharoah's snake reaction was discovered, was not ruled out by the authors as a partial component of the solid material. [10] The generalized reaction is as follows: 2 Hg(SCN) 2 → 2 β−HgS + CS 2 + C 3 N 4
In Carbon snake demo, paranitroaniline can be used instead of sugar, if the experiment is allowed to proceed under an obligatory fumehood. [11] With this method the reaction phase prior to the black snake's appearance is longer, but once complete, the black snake itself rises from the container very rapidly. [12]

A soda geyser is a physical reaction between a carbonated beverage, usually Diet Coke, and Mentos mints that causes the beverage to be expelled from its container. The candies catalyze the release of gas from the beverage, which creates an eruption that pushes most of the liquid up and out of the bottle.
