Fizzy Valentine Play Dough

Our Fizzy Coconut Lime Play Dough was the first fizzy dough we made. It was such a hit, I knew we had to try it again. This time I added a Valentine’s Day twist with hearts and pink color.


  • 1/2 cup cornstarch
  • 1/2 cup baking soda
  • 4-5 tablespoons hair conditioner
  • liquid watercolors
  • vinegar

How to Make the Play Dough

Mix together the baking soda and cornstarch. Add in the hair conditioner a little at a time. Next, add in the washable liquid watercolor. You could also use food coloring, but it has the tendency to stain. Knead the dough together until it forms a nice play dough. If it’s too sticky, add more cornstarch. If it’s too dry, add a bit more conditioner. Knead again until it feels right. If it’s too dry, it’s still a pretty cool cloud dough. Crumbly and moldable. If it’s too wet, it’s really slimy. You decide what works best for you and your kids.

We used cookie cutters to shape the dough into hearts.

Now to Make the Dough Fizzy!

The dough has baking soda in it. This will allow it to react with vinegar. Place your dough in a large baking dish or similar container to contain the fizziness and foam. The addition of conditioner will cause the reaction to foam (just like when we add soap to simple baking soda and vinegar play.)

I set out a glue bottle full of vinegar for Aiden to use. I turned the nozzle of the bottle just a little, so only a small amount of vinegar would stream out at a time. This make the exploration last longer. Adding a little bit of vinegar makes a little bit of fizz.

Add more vinegar and you’ll get more bubbles.

Continue adding vinegar. You could use a spray bottle, a dropper, or even a spoon to add the vinegar to the dough.

Eventually, you’ll get a container full of bubbles and the play dough will start to melt away.
