6) forming a natural sponge. The viscosity of the mixture can be formed into fibers, natural sponge in circular form. The trial will use a disproportionate amount of cellulose in the mixture viscosity and additive 3,4,5 and 6 weight percent of the sodium in the sodium viscous mixture ratio of 1: 1 and 1: 2, then put cattail fiber length of 5 mm. 1-2 percent by weight of the mixture viscosity. To add strength to the natural fiber sponges. As detailed in Table 1 and then forming sulfuric acid Furyk concentration of 10 percent by volume, left to form a sponge. Sheep sponge biscuit that was out of the mold, wash with clean water. Then remove water using acetone desiccation.
