Yes, without the moisture, the fet can't be managed. Here I don't use corrosive liquid, only few drops of water (2 or 3) and a few zinc oxide. Maybe content of minerals in soil + the sand + moisture acts as the zinc + the zinc oxide (many kinds of oxides exists in the soil) + water: This is the negative pole. And the positive is the solid metal, a coin for example.
