Fizzy Tie-Dye Eggs
Today we are going to be scientists! What do you think will happen when we mix a baking soda paste with vinegar? This method of dying eggs takes advantage of chemical reactions to achieve a cool tie-dye effect.

● Boiled eggs, cooled to room temperature
● Baking soda
● Food coloring
● Vinegar or lemon juice
● Large casserole dish
● Cups for each color of dye
● Optional: small dropper
- Take 1⁄4 cup baking soda and put in cup. Repeat with a different cup for each color you want to make
- Add 2-3 drops of food coloring to each cup with baking soda, using just one color per cup. Add a teaspoon of water to each cup
- Mix the baking soda and food coloring into a paste, adding a teaspoon of water to each cup. Add more water if you want a thinner paste.
- Take boiled eggs and put in casserole dish or any dish you don't mind getting messy
- Spread the different colored paste in patterns, or randomly, all over all the eggs
- Fill dropper or spray bottle with vinegar or lemon juice. Optional-just fill a cup with lemon juice or vinegar
- Spray or lightly pour the vinegar or lemon juice onto the eggs to wash off the baking soda paste. What happens when the baking soda combines with these liquids? A chemical reaction is happening, the vinegar/lemon juice and baking soda are creating carbon dioxide, a gas!
- Set eggs on clean cloth to dry, store in fridge and enjoy on Easter!
● Do you have a lot of food coloring colors at home, or just the primary ones? Mix food coloring to make new colors! Check out this color wheel here!
● Did you know that baking soda reacts to both vinegar and lemon juice? Try rinsing half your eggs off with vinegar and half with lemon juice. Do the eggs look different depending on what you used to rinse them off?
