There’s nothing cooler then finding a surprise dinosaur inside an egg, and for my Dino Dig Birthday Party I knew I had to have some kind of excavation station. That’s when I decided to make our own DIY Dino Eggs that way each kid could excavate one easily and have fun doing it.
DIY Dinosaur Eggs
I decided to make the eggs a week in advance because that’s when I had time to do it, figure out my recipe and let them dry. Here’s what you need to do. I found I was able to make 8-9 eggs per batch so you may need to make this a few times or double up the batch if need more. I wanted to make different colors so I made 3 batches.
DIY Dino Eggs Supplies needed:
- Baking Soda (we got the big bag)
- Water
- Plastic Dinosaurs
- Food Coloring
- Spatula
- Large mixing bowl
- Vinegar
- Spray Bottle
How to make homemade Dinosaur Eggs
Take 2 ¼ cups baking soda and add to mixing bowl (try to get the chunks out if there are any)
You’ll need ¾ cup water.
Add the food coloring to the water. I do about 3-4 drops.
Add the water a little at a time to the baking soda, stirring to form a paste like feel.
You may need to add more baking soda to the mix, I recommend 1 tablespoon at a time. The mixture shouldn’t be soupy.
Once you have the consistently right take a small section as your base then add a plastic dinosaur in the center and add more to form an egg. I found rolling it around in my hands helped.
After you’ve made your egg place it on parchment paper to dry for 24-36 hours

Once it’s time for the party the fun can really begin. We used different pans around the house (meatloaf, and a few cake pans) as the site to excavate the egg. Then took spray bottles filled with vinegar as the special solution. I also kept some plastic spoons close in case the kids needed help.
As the vinegar hit the baking soda the kids were so excited to see it bubbling, then as they kept going and started to chip away they couldn’t believe there was a dinosaur inside. I wish I had made more because they all asked to do a second.
It was so much fun to watch them and since it’s just baking soda, water and vinegar I knew it wasn’t harmful to them or the house.

Will the baking soda chip away without using the vinegar? My class is a second grade bunch and I was wanting to get the dinosaur skeletons for them to spend actual digging time with tools and brushes to unearth the bones.
Hi Carol, yes it will chip away, you may want to add a little water as it will become dusty, but you’ll still be able to make these and have them excavate them. The vinegar just makes them bubble up! Such a fun class project!!
Hey there, I’m looking to make them for my nephews and nieces as dragon eggs to chip away, will they dry hard enough for them to chip away at? And will baking them in the oven make them dry any quicker ?
That’s so cool. I’m not sure if they will dry faster if you bake them, but it’s possible, and they should be okay to chip at if they are dry, but be warned you’ll probably end up with a lot of dust. Please let me know how they turn out if you bake them and good luck!
I made these last week and they have been drying out. They started off blue and yellow but as they dried they got crusty on top (like a salt crystal formation) and turned yellowish (guessing the blue food dye and the yellow food dye went through a little chromatography). But think it made them looks even cooler! Can’t wait for the kiddos to spray them this weekend!
I love that they turned out so great. Have fun excavating them!
I made these and added tea grounds and a little cream of tartar which makes play dough hold together better so I figured it would with these too. The kids had a blast! The food coloring didn’t work with the tea grounds though, so they were very dark. I roles them in more baking soda to give a white shell. This gave a big initial reaction too! So fun. Will definitely do this again.
That’s awesome. Thanks for the tips!
