Colorful Eruption
An engaging and educational science experiment that combines art and chemistry, resulting in vibrant eruptions using simple household ingredients.
Ingredients
Base Ingredients
- 1/2 cup Baking soda
- 1 cup Vinegar White vinegar is preferred
- 1 tablespoon Dish soap Clear liquid soap can be used for less foam
- various Food coloring Use multiple colors for a rainbow effect
Materials Needed
- 1 Container (plastic bottle or bowl)
- 1 Tray or large surface To catch overflow
- 1 Spoons or measuring cups For mixing
Instructions
Preparation
- Start by laying down a tray or setting your container on a surface that can get messy.
- Gather all your materials within reach for easy access.
Mix Ingredients
- In your container, add 1/2 cup of baking soda.
- Drizzle 1 tablespoon of dish soap over the baking soda for added bubbles.
Add Color
- Use food coloring to add a splash of color; you can use one hue or create a rainbow by adding different colors.
Create the Eruption
- Slowly pour 1 cup of vinegar into the container with the baking soda mixture.
- Stand back and watch as the colorful eruption begins!
Observe the Reaction
- Enjoy the fizzing and bubbling action; encourage everyone to describe what they see and hear.
Notes
After the experiment, rinse your container and tray with water. It's best to enjoy the reaction immediately, as the ingredients will lose potency once mixed. Pair this experiment with a lesson on acidity and alkalinity.
