Baking soda and colored vinegar eruptions have been one of our daughter’s favorite activities for years. What’s not to like? They’re fun. They’re fizzy and they’re colorful. They are so beautiful that we have even made a few art projects using the eruptions. For Valentine’s Day this year, we made Fizzing Heart Art. The fizzing hearts were such a hit, that we wanted to try it again. The plan was that we were going to make red, white and blue fizzing stars for the Fourth of July, but my daughter stumbled across an idea of her own. We have been doing a large number of printing projects lately, so my daughter turned our original project into these beautiful baking soda eruption prints.

Results on this project will vary depending on the amount of baking soda used, paper and color concentration.

What you will need:

A cookie sheet

Baking soda

Vinegar

Food coloring gel

Watercolor paper (recommended)

Paint cups

Squeeze bottle (optional)

Medicine dropper or pippette

Wax paper

Directions:

We started by filling a squeeze bottle with the baking soda. You can just use a spoon to spread out your baking soda, but my daughter prefers using the squeeze bottles,

Next, mix your colored vinegar. I used about 1/8 of a cup of vinegar and a few drops of food gel for each color that we wanted.

Squeeze the baking soda out onto the baking sheet.

Use the medicine dropper to suck up one of the colors of vinegar and squeeze it out onto the baking soda.

Watch the reaction that occurs.

Continue to add the colored vinegar all around the cookie sheet until you have hit every bit of baking soda. Look at how beautiful the colors look.

Lay a piece of watercolor paper over the top of the cookie sheet.

We do recommend watercolor paper, but copier paper will work, as well. It will just be very flimsy and delicate until it dries.

Carefully lift your dipped paper and place the paper on a piece of wax paper to dry.

We continued to add baking soda and vinegar to form different prints. We made several prints. They came out so lovely. My daughter thought they looked like galaxies. What do you think?
