My little girls are enchanted with all things music and magic. These Frozen Fizzers are a great way to combine those loves for a spectacular introduction to science! They take egg dyeing to the next level!
The Frozen Fizzers are a child-safe chemical reaction that is so much fun to watch! When you add glitter and confetti you can see the snowflakes and glitter bursting from the fizzer, just like in the movies!
The small pipets I recommend for this activity ensure that the activity lasts a while, or if you want a big bang, dump all the vinegar at once and watch it bubble!

Be aware that vinegar is a mild acid and can cause skin irritation. Make sure your child doesn’t touch their eyes or drink it undiluted. Have a wet rag ready to dilute and wipe it from their skin if they touch the vinegar directly. Once it reacts with the baking soda, it is diluted and less acidic.
Supplies for the Frozen Fizzers Activity
- 16 oz Baking Soda
- 1/2 cup water
- Vinegar ( I recommend a gallon jug, just so you don’t run out by the time you get to all the fizzers.)
- Cube and Sphere Ice Cube Molds (these are the ones I have but there are many options)
- Food Coloring
- Snowflake Sequins
How To Make the Frozen Fizzers
You’re going to want to work quickly when you make your mixture. The baking soda will not actually dissolve into the water so it will separate. The faster you can get the mixture into the mold the better!
Steps to Make the Frozen Fizzers
1. Take a 16 oz box of baking soda and combine with 1/2 cup of water. Mix together until you have a thick paste.
Consider having extra boxes of baking soda on hand. The first box will make enough to fill 4 cube molds and 6 sphere molds. The sphere molds tend to settle and you may want to add extra as they settle.
2. Once you’ve got your paste, separate into bowls for each color you would like to put in your Frozen Fizzers. Add a generous amount of food coloring to each! They will look bright before they freeze but as the water naturally separates from the spheres it will take some of the color with it.
3. Add the snowflake sequins into the mixture.
4. Click here for the sphere instructions. For the frozen ice blocks, simply add the mixture to the mold. I suggest adding multiple colors to each mold. As they dissolve with the vinegar the individual colors will come out in the vinegar. It’s a great show!
5. Freeze the mixture for a minimum of 2 hours. I prepare the girls’ activities the night before so an overnight freeze worked perfectly. When I tried to make these during the day an hour left them soft and I had extremely colorful fingers.
Keep them frozen until you are ready for the reaction.
6. If you’re making this into a science experiment, give your child a bowl of vinegar and a pipette. Show them how to sprinkle vinegar over top of the fizzer and watch the reaction!
When dying eggs, dump a generous amount of white vinegar over the fizzers and your hardboiled eggs.
For an even bigger reaction, mix a tablespoon of V05 per cup of vinegar and watch the reaction explode! Be sure to have a towel, a bin, or mop ready! This reaction doesn’t dye eggs well.
This activity definitely counts as a sensory activity! Vinegar’s strong smell helps their olfactory senses. As the reaction occurs you can hear the fizzing of the galaxies for auditory stimulation. And, as the stars shoot out from the galaxies, as they dissolve, or the bubbles fizz up, your child will be using their visual tracking skills. Way to go, mom or dad!

I hope your kids enjoyed the Frozen Fizzers as much as mine did! Enjoyed this post and want more ideas? Please subscribe and I’ll let you know when the next post comes out. Thanks for reading!
