Today we are going to make some magic with milk and my son and daughter will absolutely love it. I have been hoping to do something special with them in a while and this will be.

Make plastic from milk.

Before 1945 plastic products were made from milk, also known as casein plastic. After 1945 synthetic plastic was introduced.

Today we are going to make some plastic letters or toys depends on what mold you can get a hold of.

You will need the following:

  1. Stovetop or microwave to warm the milk.
  2. Milk (The lower the fat content the better.)
  3. White vinegar/ Lemon juice
  4. Bowl
  5. Spoon
  6. Strainer (If you don’t have one, you can create one with a cheesecloth.)
  7. Paper Towel
  8. Molds (Lego mini figures or any mold you can get a hold of)

This experiment will take about 30 to 90 minutes to be done, but up to 2 days for the drying of the figure. If you want to paint your figure add an additional day.

Instructions

  1. Measure out 1 cup of milk. (Makes about 4 mini figures)
  2. Heat the milk on the stove top. The milk must just be steaming.
  3. Remove from the heat and then add 4 teaspoons of vinegar or lemon juice. Stir gently.
  4. NOTICE that the milk immediately begins to curdle.
  5. Stir gently for approximately one minute. This is for the full reaction to finish and al the curds form. REMEMBER to be gentle.
  6. Then strain of the whey using the strainer.
  7. Let it drip for a few minutes until all the liquid has drained off.
  8. Remove the curd.
  9. Place them in a few layers of paper towel.
  10. Carefully pat and squish to remove more of the liquid.
  11. Repeat a few times until you have removed as much of the liquid as possible.
  12. Start squishing the curd together, shaping the product.
  13. If you would like to make your product smoother, soak the curd in vinegar for an extra hour. Repeat the drying process.
  14. Start shaping and molding your curd into the desired product.
  15. The drying process will take approximately 2 days, depending on the temperature in your area of the world. Here in Namibia, it takes approximately a day.
  16. After it is dry you can use dry markers or acrylic paint to color our product.

Making it special for my kids

I have found a J and A letter mold to make the first letter of their names with them.
They had a wonderful time creating, molding and coloring their letters. We are planning to use the same method to created Christmas tree decorations by the end of the year.

Remember to spend quality time with your children, do special things, because this is precious moments that they will always remember and cherish.
