Introduce a fun science experiment for your kids. Do you know what will happen if you mix milk and vinegar? This one is really easy, fascinating, and smelly to do, and the ingredients do not cost so much. It does only take a couple of minutes if you don’t count the days it needs to dry. Best of all, you only use all-natural ingredients, 100% free from unhealthy chemicals.
Your kids will definitely have a lot of fun!
My kids just loved this science experiment. I hope yours will too!
Step 1: Heat up one cup of milk in the microwave oven for 1-1,5 minutes. You want the milk to be warm, not boiling.
Step 2: Stir in 4 tablespoons of vinegar.
Step 3: The milk will start to clump as the acid in the vinegar breaks down the protein in the milk. Stir for about 1 minute.
Step 4: Strain the milk through a strainer. Really push on the clumps to get all the liquid out.
Step 5: Transfer the clump to some paper towels.
Step 6: Continue to press all the liquid out of the plastic milk. Try to get plastic milk as dry as possible.
Step 7: Form the plastic milk in any form you want. We chose to do a heart with a cookie cutter. You can also color it with a few drops of food coloring if you wish. We chose to leave it white.
Step 8: Let it dry for a couple of days. I guess it will smell vinegar forever, even when it has dried. Now the heart is ready to be hung up in a window, on a door, or used to decorate a Christmas tree! Just use your imagination.
