FIZZING MOON ROCKS

Let’s get right to learning how to make these fizzing moon rocks for the upcoming lunar landing anniversary. Head to the kitchen, open the pantry and grab the simple supplies to whip up this fizzy mixture. Make sure to have plenty of baking soda and vinegar on hand because your kids will want to make tons of these cool “rocks”.

YOU WILL NEED:

• Baking Soda
• White Vinegar
• Water
• Black, blue, purple food coloring
• Glitter
• Pipette, meat baster, squeeze bottle

MOON ACTIVITY SET UP:

STEP 1:  Add a few cups of baking soda to a bowl. This will be a recipe you play by ear depending on how many moon rocks you want to make!

STEP 2: In a separate container color the water as desired. We chose a dark spacey theme. Just remember once it mixes with the white baking soda, it won’t be as dark.

STEP 3: Slowly add the colored water to the baking soda a little bit at a time. Add a few shakes of glitter if desired.

TIP: You want to aim for a crumbly mixture that makes a “snowball” when packed together.

STEP 4: Shape the mixture into your moon rocks. They don’t have to be perfect and can be any size. You can wrap in saran wrap to help keep the shape in the freezer.

STEP 5: Let them harden in the freezer for a half hour or more.

STEP 6: Put the moon rocks in a baking dish and set out a bowl of white vinegar with a pipette, baster, or squirt bottle.

STEP 7: Make them fizz! Using your chosen tool for experimenting, have your kids squirt some vinegar onto a moon rock and observe what happens! Because the moon rocks were frozen, they should last a bit longer during the fizzing step for more fun!

FIZZY MOON ROCK TIPS FOR HOME OR CLASSROOM

This is a super simple mixture to whip up for any theme! Think snowballs for winter!

• If your mixture is too wet or runny, add more baking soda.
• If your mixture crumbles apart after you pack it together, add a tiny bit more water!

Make sure to do this activity with the moon rocks in a baking dish or tray as it can get messy!

Encourage kids to get their hands into this one! Feel the fizz, see the fizz, hear the fizz! Don’t like the smell of vinegar, use lemon juice instead!
