You’ll see carbon dioxide bubbles forming on the eggs as the vinegar reacts with the calcium carbonate in the egg shells.

2. Spread and smooth a layer of whipped cream across the bottom of the container and drip food coloring all over the whipped cream.

The science behind the fun: Food coloring is an acid dye, so the vinegar (acetic acid) helps it form chemical bonds with the egg shell, dying the egg.

Between basketball games and homework this weekend, we stood barefoot on cartons of raw eggs and painted hard boiled ones with lemon juice and baking soda.

Why the eggfest? We’re making videos for some April KidScience app experiments!

Here are a few still shots of our lovely creations:

We soaked hard-boiled eggs in cabbage juice overnight. Then, we painted them with citric acid (lemon juice) and sodium bicarbonate (baking soda.)Click here for detailed directions and more about the science.

Make your own egg dye!  Boil colorful fruit, vegetables and spices with 4-8 cups water and a few Tbs. of white vinegar.  When the water is boiling, add raw eggs and boil for 10 minutes.  The pigment in the fruits and veggies will be absorbed by the egg’s porous surface as they cook.  Let the eggs sit in the dye until cool.  Then, wrap the wet eggs in onion skins or rub with paprika for yellow.  We had the best luck with blueberries, curry and red cabbage.  Experiment  to see what makes the best colors!  What worked best for you?  Coffee?  Tea?  rhubarb? Don’t forget to eat your creations.  Hard-boiled eggs make a great snack!
