Glowing Fizzy Eggs

Glowing Fizzy Eggs, safe for even the littlest kids baths!

With Easter right around the corner, I wanted to make something fun for the kids Easter baskets and I thought that bath bombs would be a fun and practical Easter basket filler. And, because I always like to take things up a notch, I wanted to figure out how to make them glow! The mission was a huge success, our glowing fizzy eggs are full of fun and science, plus as a bonus, your kids might be cleaner!

We had all of the ingredients left over from doing our Kandinsky Citric Fizz experiment last week, and upon learning about a safe and edible, fluorescent vitamin from Fun at Home With Kids in her Safe and Edible Glow Water post, these fizzy eggs were born!

Glowing Fizzy Eggs Recipe

  1. Gather your ingredients.
  2. Mix all of the dry ingredients together, including the powder from six vitamin B-50 capsules.
  3. Mix all of the wet ingredients together separately, include your essential oils or colorings you want to use.
  4. Slowly drizzle in the wet ingredients to the dry while continuously stirring. If you pour too quickly you can cause premature fizzing.
  5. Mold the now damp powder in to eggs either by squeezing and shaping it with your hand or by using plastic eggs as molds.

Let them dry or use them right away, it doesn’t make a difference. Head to the bath when you’re ready and use 1-2 eggs per bath, it’s REALLY bright and completely safe if a child happens to drink a little!

The citric acid and baking soda create an endothermic chemical reaction when they hit the water which is what causes the fizzing. It also feels cold in your hand since the reaction is consuming heat! They’re so much fun to play with and completely safe!

Glowing Fizzy Eggs, safe for even the littlest kids baths! Once we had dissolved two eggs in our water, I turned off the light and turned on our blacklight flashlight! The glow is really intense!

Glowing Fizzy Eggs, safe for even the littlest kids baths! The kids had so much fun pretending all sorts of things! At first it was alien water, and then it became a magic potion as they mixed it together in their cups. Eventually, Aurora became a super mermaid, I guess that her potion was radioactive and gave her super powers?

The recipe made nine eggs, so I’ll be saving the rest to use as Easter basket fillers. Not only are they super fun to play with, but the kids skin felt so soft and moisturized after they got out… I almost want to sneak a few out to use for myself!

    • Yes, although I think I may need two flashlights for each of my kids… holding the light is often their favorite part!

  1. How much citric acid do you add? It’s not listed on the recipe. Thank you for the fun idea!

    • It doesn’t have to be exact, Cherie, just sprinkle about 1/3 a cup on if you’re using a pan the same size I did. :)
