A detailed view into the structure and properties of eight different sponges to identify the most suitable sponge for day to day life. To effectively determine the results of our trials, we used a wide variety of sponges. This included cellulose sponges as well as both natural and synthetic sea sponges. The sponges that we selected had varying densities, materials, and structures, which made for interesting outcomes with differing results.The factors analyzed include the quantity of absorption, drying time, the speed of absorption, the rate of penetration, and the capacity of desorption of the sponges in question. We concluded our results based on the evidence from our experiments as well as the internal structure of the sponges that we observed through a microscope. Throughout each of our experiments, we explored the concept of adhesion, cohesion, and capillarity in relation to the porosity as well as the structural forms of the sponges to conclude which one was the most effective. We found that the key components that played into the products of our trials were the sizes of the pores and the thickness of the filaments. Our conclusive results revealed that the Quick Eraser sponge was the most practical sponge of the eight ones that were used. This surprised us and we would enjoy diving deeper into this subject and exploring more about sponges in the future.
