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