Ingredients

n Vinegar

n Baking soda

n Food coloring

n Eye dropper

n Paint brush

n Hard-boiled eggs

Instructions

n Step 1: Add food coloring and water to the baking soda to create a paste.

n Step 2: Using the paint brush, paint the hard boiled eggs with the food coloring, water, and baking soda mixture.

Explanation

When you squeezed the vinegar over the hard boiled eggs, which were painted with a mixture that included baking soda, you caused a chemical reaction that created carbon dioxide gas. The vinegar helps the food coloring bind to the shell of the egg creating a unique and colorful design.
