This food-based chemistry experiment is not to be confused with the carbon snake, which uses concentrated sulfuric acid instead of baking soda. In either case, don’t eat the resulting snake, and only touch it once it jorja fox husband has cooled completely. It is believed the experiment at Manly West was the “carbon sugar snake”, which typically involves ingredients such as bicarbonate soda, sugar and a flammable liquid such as methylated spirits.
Keep a bowl of water nearby during the experiment. Make a small indentation in the sandpile in your baking tray . A column of porous black graphite formed during the experiment. Hi, I am Shraddha Fogla and I am a mother of two beautiful boys, one 5-year-old and the other 2. I would like to share some great tips on children’s activities to help boost their mental, sensory and motor skills.
Sugar’s shifting shape allows it to enter into a multitude of associations, form and function pervading popular imagination and our physical bodies. Sugar’s various associations, and the playfulness it embodies in our imaginations, is touched on in this edition in the illustration by Rob Bidder and my interview with performance artist Bobby Baker. As much as we know about sugar’s untrustworthiness, its corrupting influence, it still has the power to charm and comfort us when we need it to.
Sugar as we know it is a carbohydrate – a construction of carbon, hydrogen and oxygen molecules. When you burn sugar with sodium bicarbonate, a carbon ‘snake’ appears. As the pile of materials react and burn, the hydrogen and oxygen get ripped from the mix, sending water vapour and pure carbon curling out from the top of the pile.

It might be the reverse today, like bread, where the unrefined or raw product is seen as more ‘refined’, artisan, healthier, or with a more sophisticated flavour than the ‘ultraprocessed’ food. Sweetness comes in many forms, but sucrose has historically held the most power over us. Sucrose, the refined white or brown table sugar we are familiar with, is made of glucose , and fructose .

This Sugar Snake demonstration was a chemistry experiment conducted during Science Week at SKH Lam Woo Memorial Secondary School on 5 April 2018. And the student lab demonstrators are Yanty, Jessie and Agnes. She is interested in how sugar’s materiality manifests itself in and out of our bodies. This is a single crystal of pure sucrose that has been allowed to slowly grow to about a centimetre. If you keep adding sugar to water, it will eventually become super-saturated – no more will dissolve. The idea of sugar, as an alluring desirable sweetness, exists as a cultural construct.
The reaction is exothermic, producing enough heat that it may shatter the container. Your carbon sugar snake is the product of three chemical reactions that are all dependent on heat. Commercial light, dark or soft brown sugar is white sugar with the molasses added back in at the end of the refining process to create the different texture, colour, flavour and cooking qualities. The rapid production of carbon dioxide inhibits the combustion reaction, leaving a significant proportion of the reagents behind as carbon. The demonstration is an example of an intumescent reaction – one in which a substance expands significantly through chemical means upon exposure to heat.
