You can adjust SG by adding things to water, i.e. salt water has higher SG than pure distilled. You can also try glycol, or experiment with oil solutions.

This is a different effect than btrueblood's bubbles.
Depending on what you are doing you may want to stir and skim. Then settle and skim. Then repeat. Light stuff can get trapped under heavy stuff. If you stir it gets free and floats to the top.
Be aware that it can take weeks for everything to settle out. Smaller particles settle more slowly.
Depends on how many kinds of plastics you have. I wouldn't think you could do it using mixed household plastics.
Do you know about surface tension and buoyancy? Don't forget about gold panning.
