The fun will be bubbling over with these fizzy Easter eggs! This exciting activity is part science experiment and part cool spring craft and art project. It's perfect for kids and adults alike, and you only need a few simple ingredients to create your own colourful, fizzy reactions.
Add 1 Tablespoon of baking soda to a small bowl or section of a deep paint palette. Repeat this for as many colours as you'd like. (If you want 6 colours, you'll need 6 small bowls with 1 Tablespoon of baking soda in each.)
Add 1 Tablespoon of water to each bowl so you have a 1:1 ratio of baking soda to water.
Add about 6 drops of food colouring to each bowl. (Some lighter colours will need more.)
Use a clean popsicle stick or spoon to stir each colour, mixing the baking soda and colour into the water.
Step 3: Paint the egg
Hold a hardboiled egg above a clean bowl.We recommend wearing nitrile gloves to dye your eggs so you don't dye your fingers too!
Using a paintbrush, add some of the baking soda paint mixture to the egg. Make sure you're getting the "sandy" part of the paint, not just coloured water. For a true "marbled" look, add the same colour to different sections across the egg.
Repeat, adding different colours of paint to the egg.
Step 4: Add the vinegar
Set the egg in the empty bowl and pour vinegar on top of it. Pour slowly so the chemical reaction doesn't erupt over the sides of the bowl.
Let the reaction settle down and the marbled egg design will appear.
Rinse the egg under cold water to remove any remnants of the baking soda paint.
Your fizzy Easter egg is complete!
Each egg you make will have its own beautiful, unique look!
