We love to experiment with baking soda and vinegar!
It’s such a fun way to bring science to life! We’ve played with baking soda “dough” to make fizzy cupcakes and we’ve explored art and science with ice on the light table, but this was the first time that we tried dying baking soda to make a fizzy rainbow.
And, let me tell you, it was gorgeous!!
When I was a preschooler teacher, I saved any baking soda and vinegar experiment for rainy days. My kids would sit and experiment with the trays for over an hour. Have you ever met a preschooler?? They don’t sit still long! You can imagine why I saved this for when we were stuck inside!!
We first came across dying baking soda on this post over at Where Imagination Grows. And, we were inspired to make a rainbow!
Supplies for Baking Soda and Vinegar Experiment
- Baking Soda
- Syringes (or eye droppers)
- Food coloring
The only “hard” part about this baking soda and vinegar experiment is mixing the colors. Here’s exactly how we dyed the baking soda:
- Scoop 4 BIG spoonfuls of baking soda into a bowl
- Add 2-3 drops (or more if you’d like) of food coloring
- Pour a small amount of water into the bowl (like a teaspoon or two)
Note: I added a drop of food coloring to the water to help brighten the color of the baking soda!
There will be little clumps of baking soda from the moisture, but the baking soda shouldn’t be wet.
Then, I put out a jar of vinegar with some syringes for my three-year-old to experiment and to play!
Don’t you think it looks gorgeous??
