Styrofoam Cups

Styrofoam cups are generally a bad idea since they aren't recyclable. But sometimes you just get one with out much of a choice. One thing that you can do with them is use them to make an insulated cup. Take a regular cup and put it inside the Styrofoam cups, and it adds a layer of insulation. While there isn't much you can do to recycle the Styrofoam, you can reuse it.

Though it's still generally better to avoid Styrofoam all together when ever possible.
