Want to take egg-dying up a notch the easy way? Marbling eggs using whipped cream and food coloring is a great project for little ones and the results are downright gorgeous!
Hint: Wear disposable glove to prevent your fingers from getting stained.
-hard boiled eggs
-a shallow container
-cool whip or whipped cream
-food coloring (neon, if you can get it)
-a chopstick or toothpick
1. Soak eggs in vinegar for 5 minutes.
2. Spread and smooth a layer of whipped cream across the bottom of the container and drip food coloring all over the whipped cream.
3. Swirl the drips into patterns using a toothpick or chopstick.
4. Remove eggs from vinegar, blot them with a paper towel and roll them through the food coloring. Put them on a plate to dry.
5. When the eggs are dry, wipe the excess whipped cream and color from the shells.
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:
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!
