ABSTRACT
The method described in this paper is based on the low velocity of free falling sand grains in water. Section 2.1 describes the method in detail. Section 2.2 shows the calculation of the dry weight of the model and 2.3 has a detailed description on the compaction procedures. Section 2.4 gives a short insight on how this method works with viscous fluids and Section 2.5 gives some remarks on the procedure.
