Ingredients:

1. Glass vase
2. Large pan to contain the mess
3. White vinegar
4. Baking soda
5. Food coloring
6. Glitter is optional

Steps:

1. Place the vase in the pan. Add 2-3 tablespoons of baking soda to the vase.                    
2.  Add 6 -7 drops of food coloring and 1-2 teaspoons of glitter to the vase.                 
3. Quickly pour in about 1/2 cup of vinegar and watch what happens next! Add more vinegar if needed.                                                                                                                            
4. After the eruption, try repeating the experiment with other ingredients around the house. What does pepper or salt look like in the volcano?  Does adding dish soap change the results? What about adding olive oil? Play around with different materials, make predictions! Remember to clean up all the mess when you are done.
