Re: casein plastic..
Safety glasses are not uncool my friend. Losing an eye for whatever reason is very uncool though, so always make sure your smarter than the average person and wear your safety gear! (I have to wear them at work sometimes, when dealing with hazardous chemicals. They may look dorky, but who cares really?)
Interesting read though! Maybe if you have a camera phone you can snap off a few pictures for us?
Here is the wikipedia page for Casein. It has many uses! :up:

Re: casein plastic..
Another way of casting plastic, is to buy some Oomoo 30 Silicone, and pour that over whatever you want to make a mold. Then buy some Smooth-Cast 320 and pour that in the molds and voila. I've seen it used a few times. Especially when making buttons for console controllers.
