Fizzing Alphabet Eggs: Letter Recognition Activity

Hatching alphabet eggs is such a fun activity! Colorful baking soda eggs hatch to reveal letters your little one will love to find!

Social media can really be an amazing place to share ideas and gain inspiration. At least once a day I see something on my timeline that inspires me to create a new project. When I saw this video on Playfull Facebook, I knew we had to try it out! With a little extra color and swapping dinosaurs for letters, we were able to make this project our own and we LOVED it.


Making Alphabet Eggs

To make the alphabet eggs, start by writing each letter on a water bottle lid. You could use anything here! I originally was going to use her alphabet puzzle pieces but they were too large and I would’ve needed WAY more baking soda to create 26 big eggs.

I then poured the baking soda into 4 containers, because I wanted the eggs to be different colors. This is of course just being extra, you could leave them their natural color. Using blue, purple, pink, and green DIY liquid watercolors, I slowly added small amounts of watercolor to the baking soda. You want the consistency to be like wet sand, wet enough that it sticks together but not too wet it’s like mud.

With our colors all mixed up I started shaping the alphabet eggs. Starting with a small amount of baking soda in my palm, I then placed the lid and shaped more baking soda on top until the lid was covered. I repeated this with each letter, and then let them dry overnight. Don’t get excited and try to touch them! It really takes a long time for them to dry, too early and they will crack!

Hatching the Alphabet Eggs

The next day I set up her hatching station. I took her outside metal bin, the eggs, alphabet mat, and spray bottle full of vinegar outside. We took the first egg and sprayed until it hatched. She was SO excited just to see the colorful bubbles forming from the reaction, but when she saw there was something inside? She was jumping up and down with excitement.

Taking the first lid, I showed her where it was on her alphabet mat. I said each letter she found, and had her repeat it. Soon she was putting multiple alphabet eggs in the bin at once, I added the colors just because but I’m so glad I did because aren’t they beautiful together? She sprayed and sprayed until ALL of the baking soda was bubbling, making all of the colors mix.

This is by far one of our favorite projects we’ve EVER done. The colors, the surprise of finding a letter inside all while working on fine motor skills and letter recognition?? 10/10 for us!
