Introduction: Easy Biodegradable Plastic
Now lots of products are made out of plastic. A lot of it is throw away and will stay in garbage dumps of thousands of years. Biodegradable plastic, unlike normal plastic made from petroleum, will decompose and become part of the soil. This Instructable will show you how one easy way to make some biodegradable plastic.
Step 1: Gather the Materials
This are lists of materials and tools needed to make the biodegradable plastic:
-Spoon/Something To Measure With
Step 2: Proportions
The proportions to make the plastic are:
1 TBSP Corn Starch: 1.5 TBSP Water: 3-5 Drops Cooking Oil
Step 3: Preparations
Mix the ingredients together to form a milky looking liquid. Once you have done this it is ready to be microwaved.
Step 4: Microwaving
Put the mixture in the microwave and set the microwave on high for 25-30 seconds. The mixture should start to bubble and should become slightly transparent. Keep an eye on the mixture to make sure nothing goes wrong.
Step 5: Molding the Plastic
When it looks slightly transparent, take it out. Let it cool a bit so you can handle it. Then knead the plastic until it is soft and can be molded like play-dough. Now you can mold it into whatever shape you want it to be. Once molded leave it for about 24 Hrs. for it to cure and become solid. It's best to keep the surface from drying out while it is curing. The image below is the plastic when shaped.
Step 6: Ideas
-You can add food coloring to give the biodegradable plastic some color.
-You can use it to make plant pots so you start the plants indoors and when they've grow you can put them in the ground.
