Water-soaked grains of carbon superconduct at room temperature, claim a team of physicists from Germany

Here's an interesting recipe. Take a spoonful of graphite powder and stir it into a glass of water. Leave for 24 hours at room temperature and then filter the powder. Finally, bake overnight at 100 degrees C and allow to cool.

And voila! A material that superconducts at over 300 kelvin--room temperature. At least that's the claim today from Pablo Esquinazi and buddies at the University of Leipzig in Germany.

If that sounds too good to be true, it's worth taking a look at the claim in more detail since there are more than a few caveats.
