I accidentally rediscovered that pseudo carbon black (soot), created by running a glass slide or other surface over a candle flame, is extremely hydrophobic. This is a ~30x image of a 20 microliter droplet of water suspended on the surface. Look at it go! The soot looks white but in person it's actually the blackest substance a typical person will ever see.
