These fizzing heart eruptions are a fun way to combine science and art with beautiful and unpredictable results.
Baking soda and vinegar eruptions are a favorite in our house. The ingredients are usually always readily available, they are easy to set up and fascinating to watch. My daughter wanted to make them this week and so we did. With Valentine’s Day nearing, we thought a fizzing heart project would be perfect.

She has recently perfected making hearts. She draws them and cuts them out all the time, so with her love of hearts and Valentine’s approaching quickly, hearts were the perfect choice for our fizzy paintings.

We cut hearts out of watercolor paper and laid them down inside of a foil lined baking sheet to help contain the mess. I do strongly recommend using the watercolor paper for the best results. I poured the baking soda into a bowl and gave my daughter a spoon to spread it out across her hearts. She wanted to do them one at a time.
We used a disposable muffin tin and mixed vinegar and food coloring gel in each section. We used roughly about 1/4 of a cup of vinegar and a couple of drops of food coloring. Food coloring concentrations will vary, so you may have to adjust your food coloring as needed. We used six colors of my daughter’s choosing.
You can use a clean medicine dropper or pipettes to spread out the colored vinegar to start your reactions.
My 4 year old started squeezing the colored vinegar mixtures across her baking soda covered heart. She squealed with excitement with each fizzy reaction. She added the colored vinegar until each fizzing heart was covered with color and the fizzing slowed down.
We tipped the excess paint off of the hearts and then set them aside to dry. Some hearts were wetter than others and some had more baking soda clumped on. The baking soda actually added a nice texture to the heart art. She did each heart one at a time and made four hearts in total.
Here are our finished fizzing hearts. Didn’t they come out lovely?
