What do you do when you have a great idea for a project with the kids, but you don't have all the items you need? You improvise, and that is exactly what I did. I wanted to make dinosaur eggs...we just didn't have any little plastic dinosaurs. Plastic ponies and unicorns to the rescue!
I must say that I did make sure to explain to the kids that unicorns and ponies do not come from eggs.
So what are dinosaur eggs and how do you make them? These dinosaur eggs are made of two simple ingredients that you likely have on hand, baking soda and water. Yes, it's surprisingly that simple. Now, if you have little plastic dinosaurs, unicorns, ponies, etc. you'll be all set.
Here's what you'll need to get started.
- Baking Soda
- Food coloring (if you'd like to make it any color other than white)
- Plastic dinosaurs (or any small plastic toy)
- A bowl
- A spoon or spatula
- Something to set the eggs on like wax paper or a cookie sheet
Making the dinosaur eggs
The amount of baking soda you use largely depends on how many eggs you'd like to make. You can easily start with less, make a few, and then make more. We started with 2 cups of baking soda and 3 tablespoons of water. We also added 4 drops of food coloring and stirred it all together. The dough was still a bit dry so we added 2 more tablespoons of water. When the dough thickens, place the plastic toy in your hand and press the dough around it forming an egg. Set the eggs on wax paper or a cookie sheet and allow them to harden. We left ours overnight. Doing so allowed this to be a 2 day experiment.
Breaking the eggs open
This part is really fun. We decided to try 3 different ways of getting the toys out. First we dunked one in a bowl of water and watched it foam. Then we chiseled one out. The third method was the most fun however. I placed vinegar in a spray bottle and let the kids spray the eggs. It was a lot of fun watching the eggs bubble up and open revealing the ponies and unicorns.
Give it a try and let us know how it went.
