Make your own dinosaur egg bath bombs, and put a tiny dinosaur hatchling surprise inside! The kids will love decorating them with food coloring markers, and you will love saving the money on expensive bath bombs from the store.

In our house, bath time is pretty much the highlight of the day for my boys. They toss every toy in their arsenal into the tub: Transformers, alligators, Z-bots (remember those? I don’t….They were my husband’s. That’s right. He saved them from his childhood and proudly passed them on to his boys)–and last, but never least, dinosaurs. What’s bath time without an epic battle culminating in someone getting eaten? A shame, that’s what.
My kids are nuts for them. But, honestly, they are expensive, especially for every day use times three. So I’ve scoured every cyber nook and cranny to find the perfect recipe so I could make them at home. The problem is that they can be so finicky to make. Too much moisture and they begin to fizz in the molds. Too little water and they crumble and fall apart. And then there’s humidity to factor in. And whether or not I really want to try to make another batch. Again. And even if everything else actually goes right, you have to get them out of the molds without breaking them.
Well! After a lot of diligent trial and error, I think I’ve finally got the foolproof recipe. These bath bombs contain only a few ingredients and have come together nicely every single time. Plus, they have a secret dinosaur inside waiting to be hatched in the bath!
- 1 c. baking soda
- 1/2 c. citric acid
- 1/2 c. Epsom salt with coconut oil (I used these relatively cheap salts)
- essential oil, as desired for fragrance
- leftover plastic Easter eggs that open up to use as molds
- gel food coloring
- 1/2 tsp. (2.5 ml) of tap water
- Wilton FoodWriter Edible Markers
A quick note about the ingredients: I didn’t add any type of oil to the mix because the Epsom salt already had oil in it. I did use (cheap) essential oils when I began making the bombs, but over time I grew tired of the strong smells. The Epsom salt is scented with a light coconut oil smell, which is actually what I prefer now. Additionally, you can find Epsom salts with other smells, such as lavender.
- Mix the baking soda and citric acid together. If you want to add fragrance, go ahead and add a few drops of that now to the mix as well.
- Mix the Epsom salt and food coloring together in a separate bowl. I didn’t measure the amount of coloring I put in. Just put something like this much:
- Add 1/2 tsp. (or 2.5 ml, to be precise) of tap water to the salt bowl (as pictured above). I used one of those droppers that comes in the Children’s Tylenol box to measure this.
- Mix the water, salt, and food coloring together until everything is evenly distributed.
- And then let it sit for about 5 minutes. This gives the moisture time to be absorbed into the salt. I’m not a scientist and I haven’t proven it, but it seems to reduce any fizzing later when combined with the baking soda mix.
- Finally, mix the salt mixture with the baking soda mixture. Use your hands to knead the ingredients together until very well incorporated. Let sit for a few minutes so the moisture is absorbed well.
If your kids are helping, this is by far the best part. It’s a lot like playing with Kinetic sand.
Do be aware that the citric acid can sting if you have any open wounds, scratches, or otherwise sensitive skin. In that case, you could wear gloves to mix. Be sure to limit the time little hands are mixing and wash thoroughly afterward.
Speaking of kinetic sand, the consistency should be very similar to that. It should stick together when pressed, but not be too wet.
If you hear fizzing, then there is most likely too much water in the mixture. You could add a bit of cornstarch to correct this if it happens.
- Next, it’s time to stuff the molds. Using the plastic Easter egg as a mold, press the mixture tightly into the bottom.
- Add a dinosaur (or other hatchling) to your egg, and then continue packing the mold until it closes tightly
So much of the fun here for my kids was deciding which creature to put in and which colors to choose.
- Most people will leave the mixture in the mold to dry for an extended period of time, usually overnight. I’ve had such bad luck getting the bombs to come out of the mold that I circumvent that problem entirely now. I actually take the bath bomb out of the mold (carefully) and wrap it in cling wrap to dry.
I twist the cling wrap on the ends to help the egg keep its shape and then let it dry for about 24 hours that way. If you lay the eggs on a kitchen towel it helps to prevent the eggs from developing a flat spot where they are sitting.
Here is our little nest of dinosaur egg bath bombs waiting to dry.
And about 24 hours later, voila! You have dinosaur eggs ready to be hatched.
We used food coloring pens to decorate and write on the eggs.
The cracking looked cute where part of the dinosaur was peeking out.
We had a good time decorating the eggs with these Wilton FoodWriter Markers.
I think we use these bath bombs just about every day. I don’t think I’ll ever be able to bring myself to purchase bath bombs again. These are just too cheap and easy to make. It kind of cracks me up how my boys are always so excited to discover which dinosaur reveals itself after the bath bomb dissolves, even though they are the ones who put the little dinosaur in and decorated the egg.
It’s the simple things. 🙂
