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!
