How to make Homemade Plastic with Milk and Vinegar

In this video, we will show you how to make your own plastic using only Milk and Vinegar.
This activity/experiment is quick and easy to make and cheap. It is a great activity to do with Children, learn Chemistry and have some fun with your own plastic sculptures afterward.

Materials needed for Homemade Plastic:
-Milk (300 mL or more, with higher fat content)
-Vinegar (2 spoons)
-Kettle
-Colander
-Spoon
-Bowl to mix it
Paper towel
Molds

Instructions for Milk and Vinegar Plastic:
-Heat the milk on the stove or in the microwave to at least 70℃ (158℉ ). We had the most success with fresh milk with 3.2% milk fat.
-Pour the hot milk into the bowl and add 2 spoons of vinegar to it. Mix vigorously for a minute or two, you should see clumps forming.
-Drain the mixture so you are working only with the solid part
-Use the paper towels (4-5) to drain that mass of any leftover water. Knead that mass with your hands and shape it into the ball
-Use the mold to make desired shapes or just shape it freestyle and leave it to dry 48h
-After that time, your sculpture got hardened and it’s done! Now you can decorate it as you wish markers or art colors
