CHRISTMAS MILK & VINEGAR ORNAMENTS
Let’s get right to learning how to turn milk into a plastic like substance… Head to the kitchen, open the fridge and grab the milk.
YOU WILL NEED:
- 1 cup milk
- 4 tablespoons vinegar
- Cookie cutters
- Paper towel
- 5/8 ribbon
HOW TO MAKE MILK AND VINEGAR ORNAMENTS
STEP 1. Add 1 cup of milk to a microwave-safe bowl and heat for 90 seconds.
STEP 2. Add 4 tablespoons of vinegar into the milk and stir for 60 seconds.
You will notice that the milk solids will separate from the liquid or whey.
STEP 3. Pour the mixture into a strainer and press out all the milk solids. Press paper towel into the strainer to remove any leftover liquid.
STEP 4. Place cookie cutters on another piece of paper towel. Then press your milk solids into the cookie cutter and use a straw to punch a hole in the top of the ornaments.
STEP 5. Let it sit for 48 hours and then carefully remove from the cookie cutter. Then decorate your ornament with a sharpie.
STEP 6. Place a piece of ribbon through the hole and tie it into a loop.
WHAT HAPPENS WHEN YOU MIX MILK AND VINEGAR
Really, this milk and vinegar experiment does not produce real plastic. The new substance is casein plastic. If you want to explore real plastic polymers, try some homemade slime!
A chemical reaction occurs between the milk and the vinegar to form the plastic like substance. When the protein in the milk called casein comes in contact with the vinegar, the casein and vinegar do not mix but rather the molecules move around and join forces to make the casein plastic!
The casein becomes these plastic-like blobs that you can strain out and mold into shapes. This is one way of making a simple cheese from milk. Who would have thought!
