Instructions

Preparation

In a clear plastic cup, measure 1 cup of water.
Add 3 tablespoons of Epsom salt or alum to the water.
Stir until fully dissolved—this might take a minute, and you’ll see the solution starting to become slightly viscous.

Adding Color

If desired, add a few drops of food coloring to the solution.
Stir gently to diffuse the color, enjoying the swirling effect.

Setting the Geodes

Pour the solution into smaller cups or molds using a funnel if needed.
Place them on a baking tray to catch any spills.

Crystal Growth

Let the solutions sit undisturbed in a cool place for 24-48 hours.
You will notice crystals starting to form on the surface and sides of the cups.

Final Assembly

Carefully remove the geodes from the cups.
Place them on top of small LED tealight candles to illuminate your stunning creations.

Notes

Experiment with different colors and shapes for unique geode designs. You can also add glitter for an extra sparkle effect. Supervise children while crafting.
