Today is all about colors! No boring eggs in a dye pot. You’ll create a color explosion right on the egg.

Your eggs will shine in bright colors, all without a brush, but with plenty of fizz! You’ll learn not only how to mix colors but also how a chemical trick brings the color to the shell. You get to stir, squish, experiment, and of course, be amazed. And if something goes wrong? No problem. That’s exactly what researchers do: they try things out!

What you'll need

Hard-boiled eggs, white
Muffin tin or glasses
Pipettes or teaspoons
Baking soda or baking powder
Tablespoon
Water
Colorful food coloring
Wooden skewers
Cooking oil
Kitchen towel

How it works

Take a muffin tin with twelve cups or glasses or bowls. In six cups, add 1 tablespoon of baking soda, 1 tablespoon of water, and a few drops of food coloring. Stir well until a colorful paste forms. Each color gets its own cup.
Boil some eggs hard and let them cool. Then place them in the six cups of the muffin tin.
Now it’s time to get creative. Take a spoon or a wooden stick and coat each egg with one of the colorful pastes. You can also mix several colors to create crazy patterns.
Take a pipette or a small spoon, dip it in vinegar, and drizzle the vinegar directly onto the colorful paste on the egg. And then: watch! It bubbles, hisses, and fizzes. The colors dance over the egg, like a little volcanic eruption.
When the fizzing stops, take the eggs out. Then you can gently wipe the eggs with a towel. The colorful patterns will appear!
If you want, you can add a few drops of cooking oil to a cloth and rub the eggs with it. This gives them a nice shine. Each egg looks different, and that’s what makes it special. Experiment, mix new colors, and be amazed by the fizz reaction.
