Crystal Eruption
Create stunning crystal formations through a fun and educational chemical reaction experiment, perfect for all ages.
Ingredients
Materials
- 1/2 cup baking soda Base ingredient for the crystal eruption
- 1 cup vinegar Creates the eruption reaction
- to taste drops food coloring Optional, for coloring the crystals
- 1 piece small container or tray For holding the baking soda and vinegar
- 1 set measuring spoons Needed for measuring ingredients
- 1 piece tray or baking sheet To catch any overflow during the eruption
Instructions
Preparation
- Cover your workspace with newspaper or paper towels to catch spills.
- Place your small container or tray on the baking sheet to contain the eruption.
Creating the Eruption
- Measure 1/2 cup of baking soda and pour it into the container.
- If you'd like colored crystals, add a few drops of food coloring at this stage.
- In a separate bowl, measure 1 cup of vinegar.
- Slowly pour the vinegar over the baking soda and watch the reaction!
Observation
- Allow the eruption to settle and notice the white, powdery crystals forming as evaporation occurs.
- Leave the mixture undisturbed for a few hours or overnight to fully dry and allow crystals to form.
Notes
Experiment with different food colorings for rainbow crystals. Increase ingredient quantities for a bigger eruption. Mixing salt can change the texture of the crystals. Use various containers for different shapes!
