Ingredients
- Baking soda
- Vinegar
- Food coloring

- Spread a layer of baking soda across a tray or a large piece of paper.
- In a separate container, mix food coloring into the vinegar. Add color until the mixture looks vivid enough for your print.
- Pour the colored vinegar onto the baking soda. Watch as the mixture fizzes and erupts.

Notes
Protect the table or work area before you begin, especially if it can stain. Supervise children during the activity, and keep the materials away from eyes and mouths.
