Baking Soda + Vinegar = FUN

There are so many twists on the classic reaction between baking soda and vinegar! Play along!

Fizzy cakes are not only a lot of fun, but they also give you an opportunity to learn about science. Here’s a recipe where you can add fun shapes and scents to this fun science experiment.

Materials needed to make fizzy cakes:

1 cup of baking soda

2 tablespoons of Kool-Aid powder (Our favorite types to use are cherry and orange flavor)

Cookie cutters

1 small glass or container

1 small tray (a shallow baking tin will also work)

1 small bowl of water

Parchment paper

1 mixing spoon

Let’s start making!

Line a tray or baking tin with parchment paper. Then place 2 to 3 cookie cutters onto the tray.

Combine 1 cup of baking soda with 2 tablespoons of Kool-Aid powder, mix well.

Slowly add water by mixing in 1 tablespoon at a time until a moldable paste begins to form.

Using the mixing spoon or your hands, fill the cookie cutters with the mixture.

Freeze at least two hours to set.

Exploration time

While you are waiting for the fizzy cakes to set, you can gather the materials needed to explore the chemical reaction.

1 small tray (a shallow baking tin will also work)

1 straw OR pipette

Vinegar (at least 1 cup)

A small container or dish

Completed fizzy cakes

Ready to create a chemical reaction?

Let the fizzy cakes sit for about five minutes out of the freezer. You can leave them inside the molds or carefully push them out. Set these cakes on a clean tray.

Pour vinegar into a small container.

By using the pipette or straw, transfer small amounts of vinegar onto your fizzy cakes. If you’re using a straw, place one end into the vinegar, put a finger over the top of the straw, and then lift. The vinegar will stay in your straw! Release your finger when you’re ready for the vinegar to drip onto your fizzy cakes.

Observe the reaction between the vinegar and the fizzy cake mixture!

 

The science behind the fun

When baking soda and vinegar combine, they create a chemical reaction. This means that these ingredients mixing generates a new substance— carbon dioxide gas. This is the same gas that is found in soda pop! Gotta love all those bubbles! How fun!
