Galaxy Moon Rocks DIY

Updated: Oct 8, 2020

Science and space sensory play

This galaxy inspired science experiment is fantastic for sensory and discovery play. Children will have so much fun making the moon rocks then equal amounts of fun discovering the surprises to be found inside!

If you have a galaxy themed party coming up, this is a perfect experiment to suit any age group!


  • Baking soda

  • Vinegar

  • Medicine dropper

  • Food colouring

  • Water

  • Plastic wrap

  • Glitter

Integrating science reactions while learning about the galaxy is an excellent way to retain information!

You will start with your baking soda, food colouring, glitter and water to create your rocks. Mix your food colouring into the water first, then add tablespoon by tablespoon until you get a texture you can form easily into a ball.

Once you've created your balls, wrap them in plastic wrap and place them in the freezer. For our experiment, we buried rocks in the middle of our moon rocks and made this an excavation activity. You can use lego people, mini cars or even old jewelry to make this more fun!

After a few hours, your moon rock activity is ready to go! Unwrap your moon rocks and place them on a play tray or cookie tray to catch the vinegar. Use a dropper and squeeze pure vinegar onto the moon rocks and watch them fizz away!

Your little one will love the reaction aspect of this experiment as much as the discovery!
