Create colorful lava cakes and learn about chemistry with this simple three-step experiment.

Fizzy Bubble Cakes Science Experiment

If you’re looking for a fun, educational activity to do outside with the kids – especially one that doesn’t require a lot of fuss – try this “bubble cakes” experiment. With just a few basic items from your kitchen, you can create miniature multicolor lava cakes while teaching your kids an important chemistry lesson. When baking soda and vinegar are combined, they form carbonic acid. Because carbonic acid is unstable, it breaks down into carbon dioxide and water. The result is a fizzy solution that bubbles and flows, much like lava. Try it out yourself by following these simple steps.


Supplies
4 tablespoons of baking soda or baking powder
1 cup of vinegar
4 or more colors of food dye (artificial works best)
Muffin tin
Measuring teaspoon
A large covered surface (this experiment can get messy)

Instructions
Fill each compartment of the muffin tin halfway with vinegar.

Add one drop of food dye to each compartment. Arrange the colors in whatever pattern you like.

Add a teaspoon of baking soda or baking power to each compartment. Watch the solution fizz and bubble up.

And there's no sensor to determine when the bag is ready, so it'll just keep cooking your popcorn until the set amount of time finishes.
