  1. Place the shark teeth in the tin.
  2. Mix 1 cup sand with 1/3 cup Plaster of Paris.
  3. Add 1/3 cup of water and mix until you have a pancake batter consistency.
  4. Pour the mixture over the shark teeth.
  5. Fill the tin nearly to the rim. You will want to leave a little space so the lid will close once the excavation is dry. 
  6. Optional - Decorate the surface of the excavation with a little glitter. 
  7. Place the Shark Week Tooth Dig in front of a fan overnight until it is completely dry.
  8. Distribute the excavation, excavation tools, and safety goggles to your Excavating Adventurer and have fun watching them dig in and discover the awesome shark teeth you have hidden inside.
