Did you know that you can make a “clay” out of baking soda and water?! This is great for babies first science experiment AND a great science activity for older kids. Even as an adult I love the bubbling of a baking soda volcano, why not turn that into a little bubbling egg with a surprise inside!
Supplies:
Baking soda
Water
Plastic Easter eggs, silicone ice cube molds, or whatever you’d like to mold it in. You could also go free form.
Little plastic animals, or whatever your child might like to hide inside.
Vinegar
Food coloring (optional)
Start by pouring a good amount of baking soda into the bowl. The amount of baking soda you will need will vary depending on how large your eggs are, luckily if you need more it is easy to make it. Gradually add water until it compresses into a “ball” in your hand. I made 3 with different amounts of water, and the one with the most water held together the best. If your mixture gets to runny just add more baking soda until it is just right. Pack some of the mixture into the bottom of your egg, then add your animal. If you want to add a couple drops of food coloring this is a good place to add it.
Next fill up both sides of the egg with the mixture and close up the egg. Doing your best to really get it pushed together.
Very carefully remove them from the eggs. If they crack your mixture may be a little to dry, but you can gently reform them in your hands. Set them out to dry for several hours. I like to put them out in the sun.
Once they are dry you are ready to go! You do want to be kind of gentile them at this stage, they are somewhat prone to crumbling. Asher is really interested in pouring right now so I let him pour the vinegar on top. You could also do this bath bomb style where you drop them into a bowl of vinegar. He thought it was so fun to find the animals inside and all the bubbling was so exciting!
I hope you enjoy this little science activity! Asher thought it was so much fun. If you try it out I’d love to hear from you! Please like, share, and play!
