Dish Soap + Water = Wet mixture → wet enough to stick together. The sand chosen must be utterly devoid of any moisture that may be present. To be sure, bake a 1-inch deep layer of it at 120℉ for 30 minutes to evaporate any water content present in it. Cool it before making the first combination.

physical chemistry

A condensed-phase (like liquid or solid) is defined, in part, by the material sticking to itself. You can have hydrophobic-water physically inside of a condensed-phase, e.g. you can have molecular-water as a minority-component of a larger material-phase in a scenario in which the molecular-water wouldn't be so cohesive, but you can't have ...

Explained: Hydrophobic and hydrophilic

Hydrophilic and hydrophobic materials are defined by the geometry of water on a flat surface — specifically, the angle between a droplet's edge and the surface underneath it. This is called the contact angle. If the droplet spreads, wetting a large area of the surface, then the contact angle is less than 90 degrees and that surface is ...
