So much better than vinegar!
If you love the idea effects of fizzy science play but hate the smell of vinegar, this is for you.
This version gives you all the fizz without the smell.
I made these the night before, and the next morning my grandkids played with them for over an hour and kept coming back all day. They absolutely loved it!
What You’ll Need
- Baking soda
- Citric acid
- Cornstarch
- Dish soap
- Optional: food coloring
- Silicone molds
The Recipe
- 2 cups baking soda
- 1 cup citric acid
- ½ cup cornstarch
- 2–3 teaspoons dish soap
- Drop just a drop of gel food coloring
Mix everything together until it feels slightly damp—just enough to hold its shape when you press it.
Add a little food coloring. Just a tiny drop. You don’t want to activate the fizz.
Press into silicone molds
Let dry overnight.
It turns into open-ended play instead of a one-and-done reaction. The dish soap makes the effect last longer. When the fizz is done, the water stays bubbly and foamy.
No strong vinegar smell
Lasts longer than a quick “volcano”
Kids can come back to it again and again.
