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]
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]

[6] In 2018, UC Davis agreed in a settlement with the United States Environmental Protection Agency to spend $14 million to clean up the landfill adjacent to the ...
English: The "Barking Dog" is an exothermic chemical reaction that results from the ignition of a mixture of carbon disulfide and nitrous oxide. Other languages Čeština: Exotermní chemická reakce "Štěkající pes" - oxidace (hoření) sirouhlíku ve směsi s oxidem dusným .
The Janus Experiments investigated the effects of exposure to neutron radiation and gamma radiation on mice and dogs. They consisted of ten large scale experiments conducted at Argonne National Laboratory from 1972 to 1989. To explore various relationships, the studies varied radiation type, dose rates, total dose and fractionation. The work ...
Bird flu has been on the rise in Washington state and one sanctuary was hit hard: 20 big cats – more than half of the facility’s population – died over the course of weeks.
Cornish played himself in the 1935 film Life Returns, which was based on the story of his experiments. The story of his experiments were featured in a 2012 episode of Dark Matters: Twisted But True. Travel Channel's Monumental Mysteries presented his experiments in the 08/08/14 episode; the segment was titled, "The Reanimator".
