Getting Ready

With a quick trip to the grocery store, we were ready to get mixin’.  (The recipe makes 5 to 6 tennis ball-sized bath fizzies.)

  • 1 cup baking soda
  • 3/4 cup cornstarch
  • 1/4 cup Epsom salt or cane sugar
  • 1/2 cup citric acid {available in natural food stores or online for canning}
  • Peppermint essential oils
  • 2-3 tablespoons unscented bubble bath
  • 1/4 clear or silver glitter {optional}
  • Large bowl
  • Measuring cups
  • Mixing spoon

Snowball Fizzies

Once I gathered all the supplies, I called my 4 and 6 year old over.  I had my kids take turns measuring out the baking soda, cornstarch, Epsom salt, citric acid, and glitter – intentionally giving them a 1/4 cup measuring cup so they could practice adding fractions.

This recipe was pretty forgiving so it makes a great hands on activity for younger kiddos as well.


Once all the dry ingredients were added we added a few drops of peppermint essential oil.  My kids loved the wintery cool scent and I loved that peppermint could help clear up congestion from winter colds.


After giving the concoction a good stir, we were ready to add the bubble bath. We were careful to add the bubble bath a little at a time so that the mixture wouldn’t become too wet.

We started with 1 tablespoon and ended up using a little over 2 tablespoons to get our mixture to clump when squeezed.

Note: The bubble bath liquid contains water and would start to fizz once added to the dry ingredients.  If you add too much, not only will your mixture be too sticky, but the citric acid and baking soda will react with the water in the bubble bath and your fizzy will lose its fizz.

If you find you added a little too much bubble bath, simply add cornstarch, a tablespoon at a time, until the mixture clumps but isn’t wet or sticky.


When our mixture clumped, we each grabbed a big scoop and squeezed it into a ball shape with our hands.  You could also use a ball mold to make the snowballs but I found the hand formed balls ended up looking a little more like real snowballs.

Once formed, we let the snowballs harden for several hours.

A little while later, my kiddos couldn’t wait any longer and came running for bath time.

I let them play with their snowball as the tub was filling.  After the snowball fizzed and dissolved, the running water made some pretty sparkly bubbles that had my kiddos begging to use the rest of the batch!


The Science Behind It

When you drop your fizzy snowball into the tub, the water sets off a chemical reaction between the citric acid and the baking soda {sodium bicarbonate}.  That’s why the dry mixture fizzed a little when the bubble bath was added. During the reaction, carbon dioxide is created making those relaxing fizzing bubbles.
