Crystal Eggshell Experiment

• Eggshells (clean and dry)
• White vinegar
• Food coloring (optional)
• Borax (available in the laundry aisle of your grocery store)
• A glass or plastic container for each color
• Hot water
• A spoon to stir

Take your clean, dry eggshells and break them in half. You can use any size egg, but the larger the egg, the larger your crystal will be. Once broken, clean the eggshells thoroughly to remove any yolk remnants.

Place each eggshell half into a separate container. If you want colored crystals, add a few drops of food coloring into each container.

Fill each container with enough hot water to completely cover the eggshells. Make sure the water is hot, as the heat helps the Borax dissolve, thus forming the crystals.

Add the Borax to the water. The amount of Borax needed may vary. The key is to keep adding and stirring until the Borax no longer dissolves, and there are some residuals at the bottom of the container. The water should look cloudy.

Leave the eggshells in the Borax solution overnight. The crystals form as the water cools down and the borax re-crystallizes.

The next morning, carefully scoop out your eggshells and let them dry. Be gentle so you don't break the delicate crystals that have formed.

Once dry, your Crystal Eggshell Experiment is complete! You're now the proud owner of some beautiful homemade geodes.

Egg Geode STEM Experiment

Ingredients

• 1 dozen of eggs
• 1 bottle of food coloring (multiple colors if desired)
• Alum powder (found at your local grocery store in their spice section)
• 1 bottle of white school Glue
• Small paintbrush
• Plastic or glass containers (one for each color of geode that you want to grow)
• Water
• Approximately 1 day of patience

Instructions

1. Crack the Egg: Carefully crack each egg around the top third or quarter. You want enough of an opening to pour out the egg and to later fill with alum but not so large that the egg is no longer egg-shaped.
2. Empty the Egg: Empty out the contents of each egg and rinse them out carefully under the tap. Let the clean shells dry.
3. Apply Glue: Using a small paintbrush apply glue all over the inside of your eggshell or if you are using a glue that your child can squeeze from a bottle, squeeze glue in the bottom of the egg and rotate the egg to let the glue spread up the sides.
4. Sprinkle Alum: Immediately after applying the glue, sprinkle alum powder on the inside of the shell making sure it sticks to the glue all over the inside of the shell.
5. Let it dry: Allow the egg with glue and alum to sit and dry overnight.
6. Prepare Alum Solution: After drying, prepare another batch of alum solution. Heat one cup of water (it does not need to be hot, just warm enough to dissolve the alum powder) and slowly add alum and stir until the powder no longer dissolves. Allow this mixture to cool slightly.
7. Add Food Coloring: Once the alum solution has cooled down a bit (wait at least 20 minutes), stir in some food coloring. This will color your crystals making geodes more visible.
8. Insert Eggs: Carefully place your egg into the alum solution. Make sure the egg is completely submerged.
9. Wait: Let your eggs sit in the solution undisturbed for 12-15 hours. The longer they sit the bigger the crystals in your geodes will grow.
10. Observe the Results: After the designated time has passed carefully remove your geodes (eggs) from the alum solution. Set them somewhere safe and allow them to dry.

Enjoy your beautiful egg geodes!
