Materials:
- Heart cut outs from watercolor paper
- Pan for containing the mess (a 9×13 baking pan works or a disposable pan)
- Baking soda
- Vinegar
- Food coloring
- Pipettes
- Cups for holding vinegar (We used juice glasses.)
Instructions:
- Mix ¼ cup of vinegar and food coloring and put into cups.
- Set up: watercolor heart cut out in pan, cup of baking soda, cup of vinegar and a pipette.
- Sprinkle baking soda over the watercolor heart cut out.
- Use a pipette to squirt vinegar and food coloring over the heart. Younger kids can use a spoon to drip vinegar over the heart.
- After the kids are done with the project, tip off the excess paint and allow them to dry.
