How to make your own crystals using a geode
Diamonds are a girl's best friend. This fun, hands-on activity allows you to create your very own sparkle. Perfect gift for the gem in your life or a colorful addition to your DIY collection.
*Alum is a type of salt that can be found at most grocery stores or drug stores. Alum makes the crystals hexagon-shaped.
Step 1: Take an egg and crack it in half (longways). Clean it thoroughly and let it dry. Once dried, use a paintbrush to coat the inside of the egg and the edges in white glue.
Step 2: Generously disperse the alum powder over the wet glue until the inside of the eggshell is completely covered. Tap out excess powder and let it dry overnight.
Step 3: The next day, fill a container with 2 cups of very hot water (almost boiling). Add 40 drops of food coloring and stir.
Step 4: Add 3/4 cup of alum powder to the colored water and stir until completely dissolved to create the growing solution. Do not leave any undissolved crystals in the bottom of the container as this will cause the alum to grow on them and not your geode. (Put it in the microwave if there are any crystals that won't dissolve). Allow to cool approximately 30 minutes before going to the next step.
Step 5: Place the alum-coated eggshell into the growing solution with the inside of the eggshell facing up allow it to sink to the bottom. Let it sit 12-15 hours. The longer you leave the eggshell in the solution, the larger the crystals grow.
Step 6: When your egg geode is ready, simply take it out and let it dry. The wet crystals will be somewhat fragile, so be careful. If you are not satisfied with the size of your geode crystals, return the geode to the solution and wait a day or two. As water evaporates from the solution, more alum will be deposited in your geode, increasing the size of the crystals.
Step 7: Put it in a safe place and don’t touch it for a day or so.
