AMAZING MILK EXCAVATION

In this fun and easy science experiment for kids, we’re going to make an amazing milk excavation by using regular milk from cows to make a plastic like substance. We will then hide a fun item to excavate in the plastic and allow it to hardened so it can be dug out and discovered later.
 
Materials:
 
  • A half a cup of milk
  • Clean jar
  • One teaspoon of vinegar
  • Saucepan
  • Small item to hide in the excavation. I love using tumbled rocks and minerals.

Instructions:
 
  1. Heat the milk in the pan until lumps begin to form.
  2. Have an adult pour off the liquid and put the lumps in the jar.
  3. Add the vinegar to the jar.
  4. Allow the lumps to soak in the vinegar for an hour.
  5. Pour off the liquid.
  6. You can then shape the ball into any shape you like around the excavation item. 
  7. Allow your amazing milk excavation to harden for several hours. After it dries completely you can paint and decorate your creation.
  8. You can now give your amazing milk excavation to someone to dig in and enjoy!
