As a child, I always wanted to see a Moon Rock. There’s just something fascinating about the moon and outer space. So when my son started asking questions about that big ol’ rock in the sky, I decided to make our own version with these DIY Moon Rocks.
This easy play recipe takes some Moon Sand and adds a bit more moisture to make it moldable to form into rocks. We made them black with some shiny glitter to simulate the sun reflecting off the surface of the moon.
DIY Moon Rocks
What you need to make DIY Moon Rocks:
- 4 cups baking soda
- 1/4 cup water
- Gold and Silver glitter
- Black food coloring
In a large plastic bin, mix together the baking soda and water. Add lots of glitter and some food coloring and stir together.
You can let your kids explore this easy Moon Sand for a bit (warning: their hands will get messy because of the food coloring!), or you can go right to making your rocks.
Mold the sand with your hand to shape it into rocks. We pressed our fingers into it to form craters on the surface.
Allow to dry overnight.
The rocks will be brittle, but kids will love examining them!
They’re much prettier than the Moon Rocks retrieved by astronauts aboard the six landing Apollo missions. Those rocks are stored at the Lyndon B. Johnson Space Center in Houston, Texas.
My son loved learning about the rocks, and how they have to be kept in Nitrogen so that they won’t get moisture. We talked about how adding moisture to the Moon Rocks would change their composition and cause them to fall apart. We even tried adding some water to our own DIY Moon Rocks!
