When these organic substances were heated, they decomposed, leaving primarily carbon, which is a black element. The chemical message in blue appears because the water in the hydrated pink crystals was removed when the paper was heated. What remained on the paper were the clearly visible blue crystals of anhydrous (without water) cobalt chloride (CoCl2). With time, the blue crystals will react with moisture in the air and re-form pink hydrated crystals. Sodium chloride (NaCl), which is ordinary table salt, is not an organic compound (it has no carbon).
If you decide to do a project, be sure to choose a topic that appeals to you. Consider, too, your own ability and the cost of materials. Don’t pursue a project that you can’t afford. If you decide to use a project found in this book for a science fair, you will need to find ways to modify or extend it. This should not be difficult because you will probably find that as you do these projects new ideas for experiments will come to mind. These new experiments could make excellent science fair projects, particularly because they spring from your own mind and are interesting to you.
Keep flammable substances away from fire. Do only those experiments that are described in the book or those that have been approved by an adult. Never engage in horseplay or play practical jokes. Before beginning, read through the entire experimental procedure to make sure you understand all instructions, and clear all items from your work space. At the end of every activity, clean all materials used and put them away. Wash your hands thoroughly with soap and water.
