3. Dinosaur Egg Bath Bombs
Dinosaur egg bath bombs are a fantastic way to combine science and play. These bath bombs look like fossilized dinosaur eggs and reveal a small dinosaur toy hidden inside when they dissolve. To make them, mix baking soda, citric acid, and a bit of water or witch hazel to bind the ingredients. Shape the mixture into egg forms around a small plastic dinosaur, then let them dry. For a more realistic look, add a few drops of green or brown food coloring to mimic the appearance of a dinosaur egg.
Kids will love the surprise of discovering the dinosaur as the bath bomb fizzes away. This idea is especially great for dinosaur enthusiasts or as part of a prehistoric-themed activity. You can even turn it into a learning opportunity by discussing how real dinosaur fossils are uncovered by paleontologists!
