Baking Soda Dinosaur Eggs are a fun and fizzy science + sensory activity where kids can “hatch” dinosaurs from homemade eggs using a vinegar reaction. Here’s how to make them:
🥚 DIY Baking Soda Dinosaur Eggs
🧂 Ingredients:
-
2 cups baking soda
-
½ cup water (adjust as needed)
-
A few drops food coloring (optional)

Small plastic dinosaur toys

🛠️ Instructions:
-
Make the Egg Dough

Form the Eggs
-
Take a small dinosaur toy, wrap the baking soda dough around it, and shape it like an egg.

Press firmly so it holds together.

Let Them Dry

Set the eggs on a tray and let them air dry overnight or place in the freezer for 30–60 minutes to speed things up.

Time to Hatch!
-
Give kids droppers or spray bottles filled with vinegar.

Let them squirt the eggs and watch the fizzy reaction as the dinosaurs “hatch”!
