When Ahsoka escorts a group of younglings to Ilum, where they seek out the Kaiburr crystals needed to build their own lightsabers in the animated series STAR WARS Clone Wars, the aspiring Jedis enter a blue crystal cave. This video depicts how to make a blue crystal cave using copper (II) sulfate powder (CuSO4). Simply saturate boiling water with your CuSO4 salt. Pour the solution (without solids inside) into a concave container, and let it cool for a few days.
You can get household copper (II) sulfate by purchasing Root Kill™ or other pool treatments and algicides. Read the ingredient list to make certain.
This experiment is popular using an eggshell to create a geode. For the original paper on Eggshell geode (1978), have a look at tandfonline.com/doi/abs/10.1080/00368121.1978.10118625?journalCode=vsca20
