Introduction: Plastic Milk
Runner Up in the
The Mad Science Fair
I was trying to find a recipe I could use to produce a chemical reaction for the Mad Scientist contest and the chemical reaction contest. I came across this one and thought is was interesting. For this tutorial I will be making Plastic milk.
Step 1: Recipe
- 2 Cups Milk
- 2 Tablespoons white vinegar
This recipe came from here: http://www.youtube.com/watch?v=pIvAl4lu1uA.
It is very helpful to view this video so you can see the process of making plastic milk.
It is a quick and easy project.
Step 2: Utensils
- Liquid measuring cup
- Measuring spoons
- Coffee filters to absorb the liquid
- Fine weave strainer
- Cookie cutters
- Skewer not shown
- Wax paper not shown, line the plate with wax paper.
Step 3: Measure/ Heat
- Measure 2 cups milk and set aside.
- Measure 2 Tablespoons white vinegar and put it into a small glass reserving until later.
- Line the strainer with 2-3 coffee filters or paper towels.
- Line the plate with wax paper.
Pour the milk into the pan and heat on stove. Do not boil! Heat until almost too hot to touch but not boiling
- Add vinegar.
- Stir gently.
- Allow it to separate into globs.
- Stir again.
Step 4: Strain
Remove from the stove:
- Place strainer in sink.
- Pour Contents into the lined strainer.
- Allow to drain a couple of minutes.
- Carefully pull up the filter and gently press with your fingers to remove liquid from ball.
- You might need to place it in another doubled coffee liner and squeeze again to remove excess moisture.
- It should begin to form a paste.
- Let it set 5 minutes.
Step 5: Molding
- Gently roll the plastic in a tight ball.
- Gently press flat to form shapes.
- This part is tricky you need to work with it and try to keep it together nicely.
- You accomplish this by pressing down and pulling toward the center with your hand.
- Using the cookie cutters make the shapes.
- Form a couple of balls if you desire.
- Using the skewer poke holes where you want if you are going to make jewelry.
Step 6: Place Shapes on Plate
Place the shapes on the plate lined with wax paper:
- Place the shapes on a plate.
- Set in a safe warm area away from children and pets.
- Allow to dry
- Turn over after a few hours to allow the back side to dry.
Please note: I made a ball because they mentioned it was rubbery and I thought I would see if it bounced. We will see.
Step 7: Uses
- Allow to completely dry before working more with it.
- You can make shapes from the plastic clay.
- Paint it when it is dry.
- Write on it.
- Make jewelry.
- If you can mold a perfect circle it bounces.
- Embellishments for many things.
- Gift tags.
- Dog Tags.
- Key ring tag.
- Picture frames?
- Game pieces.
This list is very long.
I can't wait until the paint dries so I can create something that I will post here when it is done.
Step 8: Sunshiine's Final Thoughts
This was a fun experiment. It would make a great craft project for the family.
What I did was turn milk into a solid through a chemical reaction known as a polymer molecule strand.
The individual protein strands within the milk and the vinegar solidified making plastic.
The plastic is based on a protein called casein - adding the acid causes it to unfold from its usual tangled form,and change into longer sections, which are the lumps that are removed to form the ball .
Casein-plastic used to be used to make shirt buttons.
Some cheeses (like the processed cheese slices) are made in a very similar way, so can be genuinely called "plastic cheeses".
I Painted the shapes thinking I would glue them on boxes for embellishments or make jewelry. I am very happy with the results.
Thanks you for stopping by and please check back soon as I am working on some interesting things to share.
Have a nice day!
