HOW TO MAKE A GIANT DINOSAUR EGG EXCAVATION

In this quick and easy tutorial we are going to teach you how to make a giant dinosaur egg excavation. This is a really fun way to take a regular old excavation activity and super size it for even more excavation excitement! Your kids will have a blast digging into this dinosaur egg excavation and discovering this treasures you have hidden inside.
 
Materials:
 
  • Giant plastic egg that opens vertically - This will be the mold we use to create our giant dinosaur egg excavation. I bought some giant plastic eggs on clearance after Easter this past year and you can easily find them online for sale. There are also several toys that come in oversized eggs that make perfect molds. Don't worry if you can't find that perfect egg shaped mold. Just get a large container and your children will still love the oversized excavation. 
  • Cooking spray
  • Sand
  • Plaster of Paris
  • Water
  • Container
  • Large wooden spoon
  • Measuring cup
  • Large plastic dinosaur skeleton. Make sure the dinosaur skeleton will fit in your plastic egg.
  • Excavation tools. Wooden dowels and other blunt instruments work well. Sharp tools are unsafe and not necessary as the excavations are reasonably brittle and excavate easily. 
  • Safety goggles
  • Small brush

Instructions:
 
  1. Put three cups of sand in your mixing container.
  2. Add one cup Plaster of Paris.
  3. Use the wooden spoon to mix the sand and Plaster of Paris.
  4. Add one cup of water and mix.
  5. Keep adding small amounts of water until you reach a pancake like batter consistency. 
  6. Spray the inside of your mold with cooking spray.
  7. Lay your plastic dinosaur skeleton inside the mold.
  8. Pour the mixture into the mold.
  9. Gently tap the sides of the egg mold to remove any air bubbles. This will also allow a little mixture under the skeleton.
  10. Set the giant dinosaur egg excavation somewhere safe to dry undisturbed overnight. I like to put the excavation in front of a fan. 
  11. Once the excavation has dried, gently turn it over onto a flat surface and remove it from the mold. 
  12. Allow the  excavation to dry an additional twenty four hours, preferably in front of a fan.

 

Now the giant dinosaur egg excavation is ready to be enjoyed. Find an area that is easy to clean up, distribute the safety goggles and excavation tools, and let the excavating begin. 

I hope you enjoyed this super quick tutorial and enjoy making the giant dinosaur egg excavation. These excavations are very versatile and you can put pretty much whatever you want in them.
