Ross Nanotechnology Introduction

The imagery here of chocolate sauce just rolling right off of white shoes - a particularly good color choice for the product demo - is stunning. For a brief while I even thought I understood what was happening - clearly the material is a nonpolar compound. Water's polar; anything nonpolar would 'repel' the water.

And then they started dumping oil on the product with equal success. Clearly I have some learning to do before I understand just what makes something super hydrophobic.
