A plastic eggshell is used to simulate the gas pockets that are found in some lava flows. Copper sulfate crystals in solution will represent minerals dissolved in ground water. This “ground water” will then be added to your eggshell. When the water evaporates, a genuine, simulated geode lined with beautiful robin’s egg blue crystals will remain.
