Exploding Colors Experiment with Baking Soda & Vinegar

Do you want a quick science experiment to do as a class demonstration? Well, look no further!

I wanted to demonstrate chemical reactions, and among the easiest is the baking soda and vinegar experiment.

However, simply mixing baking soda and vinegar didn’t seem exciting enough. Instead, I decided to make a game out of it!

This science experiment is really simple. You’re probably very familiar with what happens when you mix baking soda and vinegar already, but I’ll break it down below for you too.

But, first here’s what you need to conduct this “game” and experiment.

These bottles are perfect for baking soda and vinegar experiments! These are all the supplies you need for this color explosion experiment.

Supplies

  • Baking Soda
  • Vinegar
  • Food Coloring
  • Small containers or bowls

Experiment

First, drop a few drops of food coloring to each container. We did three colors, but you could do the entire rainbow and see how to colors mix too!

I then sprinkle enough baking soda in to the bowls to completely cover the food coloring. I used about 4 tablespoons.

Next, the game time begins! We shuffled around the bowls and everyone had to guess which color was going to explode. It was a good opportunity and chance to reinforce process of elimination.

Setup for this awesome baking soda and vinegar science experiment.

Everyone holds up their color card to make their guess about what color will explode.

I used these squirt bottles to make the process really easy. As soon as I add the vinegar to the baking soda, the chemical reaction occurs, and a burst of colors explodes from the bowl.

I really enjoyed seeing the baking soda and vinegar reaction with a blast of color.

Color explosion experiment results! The hidden color will be revealed once the chemical reaction happens.

What happens when you mix baking soda and vinegar?

With the baking soda and vinegar experiment, we get to experience all three states of matter: liquid, solid, and gas.

The vinegar is the liquid. The baking soda is the solid.

When the baking soda and vinegar combine, they react and generate carbon dioxide gas. That is why we see the fizzing effect. If you were to do this experiment in bottles and place a balloon over it, you’d see the balloon “magically” fill up when the reaction occurs.
