Growing Carbon “Sugar Snakes”
In this experiment, we use baking soda and sugar to create a cool black snake effect. Baking soda or sodium bicarbonate has a chemical formula of NaHCO3. When heated, it breaks down into three compounds including water (H2O) and carbon dioxide (CO2). The pressure from this gas pushes the carbonate from the burning sugar out of the sand, producing the ‘black sugar snake’.
In this demonstration, we react 30% hydrogen peroxide (H2O2)with a catalyst sodium iodide (NaI). In this reaction, oxygen gas (O2) is released in vast quantities very rapidly. We trap the oxygen gas using dish soap so that it comes out as a massive form. We add food coloring to give it some interest. The form, when it oozes out of the narrow neck of the flask, resembles toothpaste being squeezed out! Be warned. This is not real toothpaste, so please do not eat it or taste it. Please do not try this experiment at home as it uses harmful chemicals at high concentrations.
