Carbon Snake Experiment by Celine Morgan

In either case, don’t eat the resulting snake, and only touch it once it has cooled completely. Your carbon sugar snake is the product of three chemical reactions that are all dependent on heat. Beyond showing a quick and simple example of a chemical change and the production of gas, heat and light, this reaction can also be used to explore the thermal stability of carbonates.

These processes include the decomposition of sugar to give carbon and water vapor. It is this decomposition to give carbon that gives us a carbon “snake”. The mixture of sugar and baking soda in the flames will turn into a black “snake.” study abroad georgia tech If this experiment is done correctly, it is possible to grow a snake that is 15–50 cm long. This food-based chemistry experiment is not to be confused with the carbon snake, which uses concentrated sulfuric acid instead of baking soda.

If in a biology class, review the reactions for making glucose and using glucose as an energy source. Discuss the differences between glucose and sucrose. Put on acid-resistant gloves before handling the concentrated sulfuric acid.

“When these science projects are done at school and you hand them to teachers, there has to be every precaution taken especially when dealing with fire,” she explained. Preparation of highly effective carbon black supported Pd-Pt bimetallic catalysts for nitrobenzene hydrogenation. Figure 1 SEM images of the carbon foam and its carbon foil .

The first of these reactions occurs when sugar combusts in the presence of oxygen. This produces carbon dioxide gas and water vapor , which pushes more of the sugar/baking soda mixture upwards. Some of this additional sugar heats up but doesn’t have access to any oxygen, so instead of burning, it undergoes thermal decomposition, producing solid carbon and more water vapor. This solid carbon now gives the snake some shape, and also gives the snake its black color. Lastly, the baking soda also decomposes in the heat, producing solid sodium carbonate, and carbon dioxide gas and water vapor.

A confection from 1600, Manus Christi or hand-of-christ, was a preventative medicine which could include crushed pearls, spices, flower essences, medicinal oils, gemstones, gold and silver leaf. Its effect on our societal and bodily structures and our imaginations, continues to be powerful in people’s everyday lives across the world. Science ASSIST provides school science educators with information, resources and advice on school science laboratory safety. Leave the reaction beaker in the fume hood to cool.

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 process of moulding and the second refining of the sugar would happen once the sugarloaves arrived in Europe, keeping the pristine final product away from the slave labourers. The sugar plantation, factory and company owners wanted as little white sugar wealth as possible to stay in the Americas. Brown sugar came to be seen as lower class, white sugar the preserve of a more refined person. 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.

In October 2018, a similar experiment done in a lab inside a Bronx, New York high school left two freshmen students with third-degree burns on their faces bodies and arms, NBC New York reported. She is interested in how sugar’s materiality manifests itself in and out of our bodies. Refined sugar in its dormant state – a gem-like rock ready to be animated at any moment – has an otherworldly character. However, on closer examination it is deeply embedded in our world, revealing horror, folly, duplicity and rot, but also a tenderness of material texture and associations of care. It embodies the eroticism of an idealised femininity, both frosted cupcake proper and pretty, and oozingly lickably lusty. One moment it is sparkling iced perfection, hiding all sins, the next it degrades to an abject, sticky waspy mess.

The beaker appears to get hot since steam was released. New – Life Science Browse the latest tools and resources for life sciences at Carolina. Carolina Biological Supply has everything you need to complete your classroom life science activities and experiments. Next, pour the lighter fluid into the middle of the sand mound. Pour the sugar/baking soda mixture into a pile on top of the sand.

Unlike the snake produced by the dehydration of sugar by sulfuric acid, the product is safe to handle and the reaction can be safely performed in a well-ventilated room rather than a fume cupboard. Ignite sugar and baking soda to make black snakes of carbon puffed up with carbon dioxide gas. The carbon snake demo is often confused with the black snake demo. Black snakes are smaller columns of carbon produced by the reaction between sugar and baking soda. Table sugar, also called sucrose, is a chemical compound that contains lots of carbon. Sugar can be oxidized, which means that it can react with oxygen to form other products.
