C1 made the classic baking soda volcano today. They have been (and will for the next week or so) studying earth science. This is one of those classic science project projects. It’s simply. It’s safe. It uses common household materials to do it. Make a volcano cone out of modeling clay. I simply put clay around an inverted paper cup and cut out the bottom of the cup. Put the clay volcano over a small plastic container containing baking soda and flour. Combine vinegar, warm water and a few drops of red food coloring in a small bottle. Pour the liquid slowly into the container with the solids. Then stand back and watch your volcano erupt!
