How long does it take for two towels to soak up freshwater and saltwater?

The time it takes for two towels to soak up freshwater and saltwater can vary based on several factors, including the towel's material, thickness, and the amount of water being absorbed. Generally, towels can absorb freshwater more quickly due to its lower viscosity compared to saltwater, which can take longer due to the dissolved salt affecting absorption. On average, it might take a few seconds to a couple of minutes for towels to fully soak up both types of water, with freshwater being slightly faster.
