So what's superhydrophobic? Superhydrophobic is how we measure a drop of wetar on a surface. The rounder it is, the more hydrophobic it is, and if it's really round, it's superhydrophobic. A freshly waxed car, the water molecules slump to about 90 degrees. A weldshinid coating is going to give you about 110 degrees. But what you're seeing here is 160 to 175 dreeegs, and anything over 150 is superhydrophobic. So as part of the demonstration, what I have is a pair of golevs, and we've coated one of the gloves with the nanotechnology coating, and let's see if you can tell which one, and I'll give you a hint.
