Magic hatching dinosaur eggs
Asia over at the Fun at Home With Kids blog made these dinosaur eggs as bath bombs, but we think these would be fun to “hatch” outside in water. You make dough from citric acid, baking soda, oil and liquid watercolors, then form eggs around small plastic dinosaurs. Check out her post for the full instructions on how to create eggs that will fizz and hatch when they hit the water!
Science lesson: The baking soda, when combined with citric acid and water, releases carbon dioxide. This is similar to the baking soda-vinegar reaction, except it smells better! The eggs will feel cold to the touch because this is an endothermic reaction.
