A few months back Jack found this video on Youtube. I am not a crafting momma, but science experiments I can do. Science is fun!
Here is our version of homemade fizz eggs. Combine one cup baking soda with 1/4 cup of water and stir. The mixture will become a paste like consistency. Jack and Grace enjoyed using their hands to do the mixing. Then select a few small plastic oven safe toys (we used Angry Bird Star Wars toys). Cover each toy in the baking soda mixture until it is in a circular shape. Grace was a little young for this step but Jack did an excellent job.
Place the baking soda covered toys on a baking pan. Bake at 170 degrees for one hour. Remove from the oven and allow to cool completely. I did not let my kids go anywhere near the oven. This is a step for the parent, but all other parts of this experiment should be okay for your average four year old to handle.
Pour distilled white vinegar into a big bowl. You may want to place the bowl on towels because our eggs made a big mess. Place the cooled fizz eggs in the bowl of vinegar and watch the magic happen.
My kids LOVED this! In fact we just made more to let Daddy see when he gets home from work.
1 cup baking soda
1/4 cup water
about 3 cups vinegar
Mix baking soda and water in a bowl. Cover a small oven safe object with baking soda mix. Place on a cookie sheet and bake in oven at 170 degrees for 1 hour. Remove and allow to cool completely.
Once cool, put vinegar in a large bowl. Place fizz eggs in bowl. Have fun!
