Acetone and Styrofoam

The Acetone is not actually "dissolving" the Styrofoam. Here is what is happing. When styrofoam is placed in acetone, the long polymer strands are dissolved, releasing the trapped air and causing the structure to disintegrate. However, the insoluble crosslinked parts of the polymer keep the polystyrene from dissolving entirely, in much the same way as buoys on nets keep the entire net from sinking to the bottom of a lake. Once the acetone evaporates, you are left with a hard crosslinked polystyrene residue.

Gold Fingers - How to Recover Gold from Electronic Scrap
http://http://www.goldnscrap.com In this video tutorial i'm showing how to recover gold from electronic circuit board scrap. Specifically the gold plating that is found on the board connector edge - A.K.A the "fingers". This video is a complementary to the complete written tutorial on Gold-N-Scrap website (direct link below) The process applies to other kinds of gold plated itmes, given the substrate is unreactive (such as PCB, ceramic, glass etc'...). This process is less suitable for metallic items that are gold plated such as gold plated pins and gold filled items, though it will work with much effort and large consumption of acid. Post a comment and let us know how much gold do you think this recovery process yielded.
