Dinosaur Egg

7+ to make
4+ excavate
You will need:
-Plastic dinosaur toys
-Plaster of Paris
-Sand
-Water
-Large mixing bowl
*Optional*
-Large plastic Easter egg
-Vaseline

If you are going to use the plastic Easter egg you are going to want to cut the piece of plastic that holds the two halves together rub Vaseline on the inside of both sides of the egg.

In the large mixing bowl mix 2 parts sand 1 part plaster and 1 part water together.

Timing is everything here you do not want the mixture to be to runny and you do not want to wait until the mixture has completely set up either.

Scoop the mixture into one side of the egg and push the baby dinosaur into the mixture.

Add the mixture to the other half of the egg and carefully put the two halves together to make the whole egg.

Allow to dry for at least 3 hours.

Carefully open the egg and pull one half off. I found it easier to twist the plastic egg off rather then just pulling it off.

Need something a bit easier to dig into?

Try shaping mixture in your hands. This keeps the edgesit from getting too smooth and is easier to “dig into”.


Dinosaur Excavation Rock


6+
You will need:
-Plastic dinosaur skeleton puzzles
-Plaster of Paris
-Sand
-Water
-Large mixing bowl
-Vaseline

You will need to choose what you want to use for your mold. If you use a reusable container you will want to make sure that the opening is larger then the bottom so your plaster will slide out fairly easy.

You will want to rub Vaseline around the inside of your mold completely covering everywhere the plaster will touch. Set aside.

In a separate mixing bowl add equal parts Plaster of Paris and water mix until smooth. When the mixture is smooth stir in the sand.

Pour your mixture into your mold and allow to set for 5-10 minutes.

After 5-10 minutes the mixture should have set up enough to allow you to add your “treasure”. To add your treasure gently push your items into the mixture leaving enough room so that they are not touching each other.

Allow to dry for another 30 minutes.

Then turn your mold upside-down gently tap the sides and bottom until your “rock”falls out.

Allow to dry overnight then grab your tools and dig in!
