1. Create Your Own Dinosaur Egg Fossil.

2. First you’ll need to find the right balloon for your egg.

3. Then you’ll need to mix 2 part water and 1 part Plaster of Paris (Or 90 Minute quick set plaster).

4. Next, you will need an empty squeeze bottle with a tip small enough for the balloon to fit on.

5. Then, you can simply squeeze the mixture into the balloon to create your egg.

6. You will need to soak the plaster filled, balloon in a bowl or sink of water for about 30 minutes to let it harden. This way, the plaster will have less of a flat spot on the bottom.

7. Once the Plaster has hardened you can cut the balloon away from the egg mold.

8. Then, you can start to carefully carve your new Dinosaur egg. Make sure to take your time and not push to hard.

9. Finally, you have created your very own, original fossil.
