Plastic Milk

Want to make plastic out of milk? Well, you can’t actually make plastic but you can make a solid almost like plastic and it is super simple and lots of fun! All you need is a couple of things from the kitchen to get started.

Little Passports

What you will need:

• One cup of milk
• 4 teaspoons of white vinegar
• A strainer
• A pot and spoon
• Paper towel and pastry cutter
• Glitter and/or food coloring (optional)
• An adult helper

What to do:

  1. First, have an adult heat up 1 cup of milk. Do Not Boil!
  2. Next, shut off the heat and add 4 teaspoons of vinegar.
  3. Then, stir the vinegar and milk for about a minute.
  4. Now, strain the mixture. You will notice clumps
  5. Left behind in the strainer is a mass of lumpy blobs.
  6. Dry lumpy blobs on paper towel. Pat flat and cut with a pastry cutter.
  7. Set aside to dry for a few days.

How Does it Work:

Is there really plastic in milk? Well, no there isn’t plastic but their is a protein known as Casein which is found in milk. When the Casein meets acid such as vinegar, it becomes visible and forms blobs. True plastics, called polymers, are a little bit different.
