I found this video trough Bioplastic News, but it was originally posted in Green Plastics. They are actually looking for more instructive videos, so maybe we should keep an eye on them, see what else they can get. In their own words:

Would you like to make a bioplastic instructional video?

Can you create a fun and informative instructional video about bioplastic? We are looking for videos of all different types. You can demonstrate how to make a specific bioplastic product in your own home. You can test the biodegradability of various bioplastic products. You can compare and constrast the properties (strength, flexibility, etc) of bioplastic compared to regular plastic. Regardless of what you

want to show, make it fun and informative and we will feature your video here!

Enjoy the lesson!
