We’re obsessed with all things sparkly and shiny. And when we can find a fun craft, we’re all about it. The more glam, the better. So when we found out we could grow our own crystals, well, we couldn’t wait to roll up our sleeves and get started.
The best part is that this DIY is a mix of sparkle and science. Borax, which is a household cleaner you can find at a hardware or grocery store, will actually grow little geodes when mixed with boiling hot water. Experiment with different food coloring and paint to create all kind of beautiful colors and crystals. Now you only have to wait a few hours before you rock your new geodes…see what we did there?
Science gone glam is our favorite DIY for sure, and it may be your new favorite after you check out this video below!
Foam brush or paint brush
Gold leaf (optional)
1. Mold the polymer clay into a bowl. You can marbleize a few colors of clay by twisting them together, or use one clay color.
2. Place the bowls upside down on a baking tray with parchment paper. Press down the sides to flatten the edges to give the appearance of a sliced geode.
3. Bake according to the instructions on the clay packaging.
4. Wait at least 30 minutes for the clay to cool before coating the inside with glue followed by borax. Wait 1 hour to dry.
5. Fill a bowl with 2 cups of boiling water and 1/3 cup of borax. Place the clay bowl inside. Let crystals form overnight.
6. When you first pull out the bowls, the crystals may not look fully formed, but they will continue to form after taken out of the borax solution.
7. Break off the edges of the crystals to give the appearance of a geode (optional).
8. Paint the edges with gold leaf, and the inside lightly to add dimension (optional).
