Introduction: "Green" Plastic Toys
Today's plastics require oil to make but with the recent surge in oil prices and the negative externalities that result from burning oil, make making plastics a costly action to the wallet and environment. Using all-natural materials that can be found in most homes, milk and vinegar, one can make their own mold-able plastic to fit any needs including making toys.
Fun fact: During World War II, the American army used the same plastic to make windows for their bombers.
Step 1: Get Materials
Get some stuff:
milk, vinegar, a strainer, a heat-safe container, a mold and food coloring
Step 2: Prepare the Milk
Pour milk into a container and add some food coloring for some fun.
 Forgot to say:
Heat up the milk but not hot enough for it to boil. I just put it in the microwave for about 2 minutes but you can do anything in terms of heating it up
Step 3: Make the Plastic
Add the vinegar to the milk and stir it to get the most out of the reaction. I used a fork to stir it.
Step 4: Strain It
Strain the solution to separate plastic from the remaining water, vinegar and milk
Step 5: Pat It Dry
Put the plastic onto a paper towel and pat it dry with some more towels to get rid off some more of excess water
Step 6: Get Mold
A mold :)
Step 7: Place Into Mold
Put the plastic into the mold and let dry by itself for a couple days, or you could use something to help it dry like a hairdryer etc.
