For those of you who follow my activities, you know how much I love my baking soda and vinegar experiments. To be fair, the tots and my littlest superhero LOVE baking soda and vinegar so it’s not ALL about me 🙂
This one is a simple and easy addition to your space theme. I call them Jupiters (even though my color mixing wasn’t as successful as Jupiter) but you could make them any planet or leave them white for the moon.
Here’s what you need to get started:
- Baking Soda
- Measuring cup
- Large Mixing Bowl
- Tray for drying the rocks
- Black or purple food coloring (optional – but colors make everything more fun!!)
To make the planet:
Combine 2 cups of baking soda and 1/2 cup of water (add the desired color to the water) in a large bowl. To make the the Jupiters, I split this into two bowls, one with red (looked orange) and one with yellow.
Then I mixed both together to get an orange-yellow swirly Jupiter look. Kind of.
Using your hands, take a handful and roll into a ball. If it’s too dry, it won’t stay together, if it’s too watery, it will melt into a sloppy puddle. Add water or more baking soda to adjust the consistency.
The next morning, the planets were hard. Note: this recipe will yield about 10 balls.
I gave each little one a “Jupiter” and a cup with vinegar that had black food coloring and some silver glitter (“Starry Space Juice” is what I called it!).
The tots definitely know what to do with the dropper and the vinegar. Space juice was added to the planets for some fizzy fun!
Such an easy and simple little experiment to set up!

Science behind the Activity:
This is a twist on the classic baking soda and vinegar experiment. Baking soda is a base and vinegar is an acid. When combined, they release carbon dioxide gas (the bubbles). The fizzing and bubbles are just way too much fun for the kiddos!
