Space is an interesting place with so many things to explore. The moon was formed when a rock the size of Mars collided with Earth. The debris that was left in orbit formed together and that is now what we call the moon. Can you believe that the moon is 238,900 miles from the earth? It would take 98 days to run around it. That’s crazy! 

Today we’re going to learn how to make fizzy moon rocks! The kids are sure to have fun with this one!

Supplies Needed

  • Baking soda

  • White vinegar

  • Food coloring (black, purple, and blue)

  • Glitter

  • Turkey baster (or small squirter)

  • Water

  • Glass baking dish or plastic container to put the rocks in


  • Depending on how many children you are performing this experiment with will determine how much product you put in the bowl. Let’s start off with a medium bowl. First add a few cups of baking soda to the bowl and set to the side.

  • In a small bowl, add your water and drop the food coloring in.  You can always choose different colors. For this activity we chose black, purple, and blue.

  • Once the food coloring is mixed with the water, pour it over the baking soda. If wanting to add some pizazz, sprinkle in some glitter. It’ll start to become a crumbly texture that can easily be formed into a ball.

  • Roll out seran wrap on a flat surface. Form the dough into moon balls, wrap them, and place them in the freezer to help them keep their form.

  • Let them sit in the freezer for a little over a half hour. When you take them out, put them into a glass baking dish or plastic container. Put white vinegar in a small bowl.

  • Using a turkey baster, blast the moon rocks with the white vinegar and see what happens.
