Since our dissolving rocks were such a hit, I decided to do an Easter version. I used the same "recipe" to make fizzing eggs. I mixed baking soda with enough water so the dough held its shape. I also added food coloring.
|Just as appetizing as everything else that comes from my kitchen.|
To make the egg shapes, I molded the mixture around the erasers and letters and formed them with my hands. Last time we did this I let them dry overnight, but this time I put them in the oven at a very low temperature to speed up the drying time.
When we dropped the eggs into a vinegar and water mixture, they fizzed like crazy and the kids loved finding the surprises inside.
The Golden Egg Book by Margaret Wise Brown would pair nicely with this activity. A little bunny finds an egg and tries to figure out what's inside. When the egg hatches, the lonely bunny finds a new friend.
