Erupting Moon Rocks Space Science Experiment
In this fun and easy science experiment, we’re going to make space rocks that use a chemical reaction to fizz and erupt.
- Baking soda
- Black and silver biodegradable glitter
- Black food coloring
- Squirt bottle
- Add some glitter to two cups of baking soda.
- Next add a couple drops of black food coloring to ¼ cup of water.
- Slowly mix in about ¼ cup of water with two cups of baking soda. The measurements do not need to be exact. You are looking to form a doughy consistency. Too much water will dissolve the baking soda so be sure to add the water slowly.
- Form the dough into balls and allow to dry overnight. These will be our moon rocks for the purpose of this demonstration.
- Once the moon rocks have completely dried, squirt them with vinegar and observe what happens.
How it Works:
The baking soda is a base and the vinegar is an acid. When the two combine, an endothermic chemical reaction occurs which releases carbon dioxide. The release of carbon dioxide causes the fizzing and erupting effect.
Make This A Science Project:
Try different acids on the moon rocks like lemon juice and observe any noticeable changes. Place a moon rock in a zip close baggie, add vinegar, seal the baggie closed and observe what happens. Try adding salt to the moon rock mixture.
