What is the science behind egg geodes?
Place eggs in a safe place for a few days and watch as the water evaporates and crystals form! Geodes occur when gas bubbles become trapped in holes or crevices within rock. Minerals dissolved in the water seep into these spaces and slowly become deposited on the surface, creating natural geodes.
How do you make crystal eggshell geodes in 5 easy steps?
How to Make Crystal Eggshell Geodes in 5 Easy Steps
- Ingredients. 1/2 cup Water.
- Heat up the water. Bring your water to a boil.
- Add the epsom salt. Add the epsom salt a little bit at a time.
- Pour the solution into the empty eggs.
- Let the crystals grow.
How long does it take to grow a geode in an eggshell?
After 12 to 15 hours, your alum crystals will have grown! Carefully remove the shells and place them on a paper towel to dry and finish the geode-creation process. If you want bigger crystals, let the shells sit in the solution longer.
Can you make a real geode?
Natural geodes are hollow rock formations that contain deposits of crystals. Assuming you don’t have a geological timeframe to obtain a geode and don’t want to buy a geode kit, it’s easy to make your own crystal geode using alum, food coloring, and either plaster of Paris or an eggshell.
How do you make homemade geodes?
Grow Crystals
- Pour about a half cup of hot tap water into a cup.
- Stir in alum until it stops dissolving.
- Add food coloring, if desired.
- Set your eggshell or plaster geode inside a cup or bowl.
- Pour the alum solution into the geode, allowing it to overflow into the surrounding container and eventually cover the geode.
How long does it take for a geode to form?
How long does it take for a geode to form? Over thousands of years, these layers of minerals build crystals that eventually fill the cavity. How long this takes depends on the size of the geode. The largest crystals can take a million years to grow!
What do you need to make egg geodes?

- Eggs.
- Rock Salt.
- Sea Salt.
- Borax*
- Other substance that could be tested for crystallization such as sugar, epsom salts, cream of tartar, baking soda, or alum*

How do you make a homemade geode?
How do you make egg geodes with borax?
- Gather your materials!
- Start by preparing your borax solution.
- While your crystal solution is cooling down, start preparing the eggshells.
- Brush some glue on the inside the eggshell, and then sprinkle borax inside the shell.
- Fill a cup with crystal solution and add a few drops of food coloring.
Is alum and borax the same thing?
Borax (Sodium tetraborate) is used as a cleaner in many parts of the world and may be purchasable in supermarkets or home handyman stores. Boric acid on the other hand is used as a toxic pesticide. (Sodium tetraborate is a salt of Boric acid). Alum is Aluminium Sulfate.
How much are rainbow geodes worth?
Geodes Worth per Gram, Pound, Ounce & Carat
Unit | Geode Price |
---|---|
per gram | $2 – 15 |
per ounce | $5 – 56 |
per pound | $10 – 900 |
per kilo | $90 – 2000 |
How can you tell a fake geode?
Fake geodes can be identified based on how they were manufactured. Synthetic versions lack flaws that are found in natural geodes, while composites and imitations often have evidence of bubbling, cracking, splotchy paint, artificial color, and leftover glue.
What can you learn from eggshells geodes?
Although the crystals are quite strong, handle your eggshells geodes carefully. Encourage your kids to get out magnifying glasses and check out the shape of the crystals. Crystal growing is a neat chemistry project that is quick to set up and great for learning about liquids, solids, and soluble solutions.
What grade level is the egg Geode experiment?
This egg geode experiment is perfect for toddlers, preschoolers, kindergartners, grade 1, and grade 2 students. This egg science project will create a variety of different crystals all of which will hold a certain WOW factor!
What is a sparkling eggshell Geode?
This sparkling eggshell geode is a delightful science experiment that your kids will love. First, you’ll need to crack the egg. You can crack them in half crosswise like normal if you like.
How do you make crystal geodes with eggs?
You need at least 5 halves to make a rainbow assortment of crystal geodes. The egg inside can be discarded or cooked and eaten as you only need the shell. Cooking eggs is a great example of irreversible change! STEP 2. Bring 4 cups of water to a boil and stir in the borax powder until it is dissolved.
