From Wikipedia ""Wet" suppressors or "wet cans" use a small quantity of water, oil, grease or gel in the expansion chambers to cool the propellant gases and reduce their volume (see ideal gas law). The coolant lasts only a few shots before it must be replenished, but can greatly increase the effectiveness of the suppressor. Water is most effective, due to its high heat of vaporization, but it can run or evaporate out of the suppressor. "
