Fun With Ethanol

Thanks to Popular Mechanics for this little fun with chemistry trick. I had no idea that ethanol mixes could be convinced to spontaneously separate simply by adding a bit of water to the mix.

Or that the trick is easier if you add more ethanol to the mix, as the government is proposing, in spite of evidence that it causes higher pollution, increases our dependence on foreign oil, increases fuel consumption, and inflates our grocery bills.
