Soil Density/ Water Content Concern

The properties of soil can vary greatly depending on the water content, and if we don't account for that our data can be extremely erratic. I thought of a process to dry to soil post testing. We could lay it out on a large sheet of the weed block and apply pressure with some paper towels. Then we let it dry in the sun, and maybe finish it off with hair dryer. What do you guys think?
